[bsp][synopsys] add basic new embarc bsp support

Browse Source 
* the initial support of synopsys designware ARC processor
  using embARC_BSP, all synopsys ARC-based boards are
  supported:
  -ARC Software Development Platform
  -ARC EM Starter Kit
  -ARC EM Software Development Platform
  -ARC HS Development Kit
  -ARC IoT Development Kit

* The embARC BSP is a new generation embARC software development
  package.  ​It is designed to be the inter-layer between hardware and
  operating system. ​ BSP could hide the difference of hardware/boards,
  provide a unified interface to upper-layer.

* the initial support of synopsys MWDT toolchain.
  The DesignWare® ARC® MetaWare Development Toolkit builds upon
  a 25-year legacy of industry-leading compiler and debugger products.
  It is a complete solution that contains all the components needed to
  support the development, debugging and tuning of embedded applications
  for the DesignWare ARC processors.

* for detailed board information, pls go embarc.org.

# Synopsys ARC Boards support with embARC_BSP
## embARC_BSP
The embARC Board support Package (BSP) is a software distributions aimed at facilitating
the development and evaluation of embedded systems based on ARCv2 processors, which is
designed to provide a minimal board support package for ARC users by defining
consistent and simple software interfaces to the processors and onboard devices.
The embARC BSP is a new generation embARC software development package. ​
It is designed to be the inter-layer between hardware and operating system. ​
BSP could hide the difference of hardware/boards, provide a unified interface to upper-layer. ​
In the scenarios that no OS is required, embARC BSP can also standalone and work in baremetal.
embARC_BSP features:
* Support MetaWare & GNU toolchains​
* Support all development boards and tcf​
* Support various build systems and compiling environments,
such as ARC MetaWare & GNU IDE, makefile​
* Designware and Subsystem drivers, including UART and GPIO, I2C, SPI, etc. ​
* No middleware, no OS​
* Easy to port to different platform / OS​
* One example (UART, GPIO, timer)​
* Code coverage reach 100% in test. ​
* MISRA-C compliance​
* C & C++ support, assembly support
## Supported Boards
* [ARC Software Development Platform](https://www.synopsys.com/dw/ipdir.php?ds=arc-software-development-platform)
* [ARC EM Starter Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc_em_starter_kit)
* [ARC EM Software Development Platform](https://www.synopsys.com/dw/ipdir.php?ds=arc-em-software-development-platform)
* [ARC HS Development Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc-hs-development-kit)
* [ARC IoT Development Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc_iot_development_kit)
## Software Requirement
### embarc_bsp
There are two ways to get embarc_bsp:
#### use RT-Thread ENV tool:
embARC_BSP has been configured as package module, you can just run the command `pkgs --update` in <RTT_ROOT>/bsp/synopsys/boards
folder using ENV tool.
#### without RT-Thread ENV tool:
We can get it from github: [embarc_bsp](https://github.com/foss-for-synopsys-dwc-arc-processors)
The default path for embarc_bsp is <RTT_ROOT>/bsp/synopsys/boards/packages/embARC_bsp-upstream,
when you use other path, please set the environment variable `EMBARC_BSP_ROOT`.
### Toolchain
Now both GNU and MetaWare Toolchain are supported, set the System environment variable RTT_CC select the toolchain.
GNU:
set RTT_CC=gnu
MetaWare:
set RTT_CC=mw
#### GNU
The ARC GNU Toolchain offers all of the benefits of open source tools, including complete source code and a large install base. The ARC GNU IDE Installer consists of Eclipse IDE with [ARC GNU plugin for Eclipse](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/releases), [ARC GNU prebuilt toolchain](https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases) and [OpenOCD for ARC](https://github.com/foss-for-synopsys-dwc-arc-processors/openocd>)
Here, the ARC GNU toolchain is installed to `c:\arc_gnu`. If not, please change the path configuration in rtconfig.py.
When you use GNU Toolchain, you need to install [Zadig](http://zadig.akeo.ie) to replace the default FTDI driver with WinUSB driver. See [How to Use OpenOCD on Windows](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/wiki/How-to-Use-OpenOCD-on-Windows>) for more information.
#### MetaWare
The [DesignWare ARC MetaWare Development Toolkit](https://www.synopsys.com/dw/ipdir.php?ds=sw_metaware) builds on a long legacy of industry-leading compiler and debugger products for embedded applications. It is a complete solution that contains all the components needed to support the development, debugging, and tuning of embedded applications for the DesignWare® ARC® processors.
Here, the ARC MetaWare toolchain is installed to `C:\ARC\MetaWare`. If not, please change the path configuration in rtconfig.py.
## Build & Debug
### Build embarc_lib
please run the following cmds to build embarc_lib
cd <rt-thread-root>/bsp/synopsys/boards
scons --embarc_build
### Build
please run the following cmds to build
cd <rt-thread-root>/bsp/synopsys/boards
scons
### Debug
After compile, please use the following cmds to debug
scons --gdb #use gdb debugger
scons --mdb #use mdb debugger
### How to choose different boards
There are some parameters we can use in scons, for example:
scons --BOARD=emsk --BD_VER=23 --CUR_CORE=arcem9d --TOOLCHAIN=mw --OLEVEL=O2
* BOARD: choose the board, we can set: `emsk, iotdk, emsdp, hsdk, axs`.
* BD_VER: choose the board version, some boards have different versions, for example,
we can set: `10, 22, 23` for emsk board.
* CUR_CORE: choose the arc cores, some boards have different cores, for example,
we can set: `arcem7d, arcem9d, arcem11d` for emsk board.
* TOOLCHAIN: choose the toolchain to build embarc_lib, we can set: `mw, gnu`.
* OLEVEL: choose the build optimize level, we can set: `O0, O2, Os`.
For more information, you can run the command `scons -h`.
