AVR: Fix linking error for AVR platforms that have no ARCH_HAVE_LEDS defined
...
Minor bug while working on Arduino Mega support. I didn't add support
for ARCH_HAVE_LEDS and have it undefined in .config. To my surprise compilation
failed since AVR code had a related function compiled in.

AVR: Fix resulting nuttx file name when EXEEXT is not empty
...
arch/avr/Makefile is adding extra EXEEXT to the
nuttix image file. This was not discovered since in most configurations
EXEEXT is empty string.

ARMv7-R and TMS570: Re-orider some initialization logic. __start used to called arm_boot() which would return. Then __start would call os_start(). That won't work for the TMS570 if is does a destructive memory tested because the return information will be lost in the stack. Also comment a nuisance assertion. The assertion is probably correct but certainly a nuisance during initial testing

Change notation of PCH and PCL registers into PC0 and PC1
...
This is for forthcoming Atmega2560 support. The Atmega2560 has 24-bit PC
thus, PCH and PCL would become PCH, PCM and PCL (M for Middle). The problem
that in this notation PCM is equivalent to former PCH. This makes compatable
porting kind of difficult, at least for my taste.
Instead PCH becomes PC0 and PCL becomes PC1 (think of the index as order of
bytes pushed to stack when call is performed, PC0 as MSB goes first, PC1
goes to stack second, and for 24-bit PC, PC2 as LDB goes last).

AVR: Fix interrupt bombing during a context switch
...
TCB_RESTORE macro has a problem when restoring Status Register
and returning from the function (in up_fullcontextrestore()) as non-atomic action.
If there is some frequently occurring interrupt, chances are that we will
enter the interrupt handler just before ret is called.
The handler may cause a context switch which, when unrolled, will
execute up_fullcontextrestore() function that employs TCB_RESTORE.
It will be interrupted again just before return, leaving part of context
switch content un-popped again, etc... Thus, chances are that the stack will
eventually blow.
Note that this is not some edge condition fix. This bug was discovered when
testing AVR with UART configured to work on 115200 baud rate.
