Simplify interrupt and RTOS timer tick handlers
...
RTOS Timer tick handler is now the same as any other ISR.
This causes a few subtle behaviour changes that seem OK but are worth noting:
* RTOS tick handler sdk__xt_timer_int() is now called from one stack
frame deeper (inside _xt_isr_handler()), whereas before it was called
from the level above in UserHandleInterrupt. I can't see any way that
the extra ~40 bytes of stack use here hurt, though.
* sdk__xt_timer_int() was previous called after all other interrupts
flagged in the handler, now it's called before the TIMER FRC1 & FRC2
handlers. The tick handler doesn't appear to do anything particularly
timing intensive, though.
* GPIO interrupt (value 3) is now lower priority than the SPI
interrupt (value 2), whereas before it would have been called before
SPI if both interrupts triggered at once.

Move all code paths touched by NMI to IRAM
...
Prerequisite for calling Cache_Read_Disable() for OTA updates.
Massive thanks due to @foogod and their xtobjdis tool, creating the call
graph of where the wDev_ProcessFiq touched (including in newlib, etc.)
would have otherwise been very painful:

Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions
...
Closes #7 .
It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.
