Adds another configuration which includes the CGOL game application.
This gives users something animated and interesting to see on the HDMI
video output, since the frame-buffer example is not as interesting.

Introduces a very basic frame buffer driver implementation for the RPi4B
which is registered at startup and works with frame buffer graphics
examples (and LVGL). Graphics are displayed on the HDMI0 and HDMI1
output, depending which one is plugged into the display. I have not
tested using both at once, nor does the driver account for that. They
are both referred to as display 0, plane 0 since the RPi4B frame buffer
interface does not seem to have a way of distinguishing.

This initial implementation sets up support for the EMMC interfaces on
the BCM2711. Only EMMC2 is tested since it is the interface of interest
(connects to uSD card). MMCSD communication is functional and the boot
partition of the SD card can be mounted and interacted with.
Insertion/removal interrupts do not fire after initial boot, and
sdstress fails with any byte size larger than 1023. 32GB card works
perfectly, while 64GB card exhibits strange behaviour when interacting
with VFAT filesystem.

Added autoled implementation for the Pi4B. Status LED is used as NuttX
start indicator, while power LED is used for panic/assert indication.

A basic implementation of mailbox API with some helpers for accessing
properties implemented. Uses busy-wait due to documentation challenges
with mailbox API.

Initial I2C implementation such that I2C sending and receiving now
works well enough to use the BMP280 driver for a BMP280 device connected
to any of I2C0-I2C6 on the default pins. I2CTOOL also works for these
interfaces.
Functionality for "no stop" and "no start" options is not present.
Implementing that is not clear from the peripheral datasheet and will be
a challenge.

Includes a Mini-UART NSH console for the 4B, tested on the 4GB RAM
model. Part of an I2C driver which can only read, boiler-plate for a SPI
driver, and a GPIO driver with limited pins. Some tools are present for
automatically fetching the boot files and creating the `config.txt` file
based on selected Kconfig options.
