arch/udelay: Make common, weak definition of up_*delay functions

Browse Source 
Many different architectures re-implemented the exact same code for
`up_*delay` because it was originally written as architecture dependent
code. Busy-waiting can be done regardless of architecture, so this
commit moves that duplicated implementation to a common file with weak
definitions so that individual architectures (see tc32) are still able
to override the definition if needed/desired.

Default implementation is not included if ARCH_TIMER is enabled, since
it is more accurate and provides its own weak definitions to override.

* Description:
* Delay inline for the requested number of microseconds. NOTE: Because
* of all of the setup, several microseconds will be lost before the actual
* timing loop begins. Thus, the delay will always be a few microseconds
* longer than requested.
*
* *** NOT multi-tasking friendly ***
*
* ASSUMPTIONS:
* The setting CONFIG_BOARD_LOOPSPERMSEC has been calibrated
