92eb02f17a Simplify linker script to remove preprocessing, not check flash sizes 
Memory layout is now split into two linker scripts for OTA vs
non-OTA (different starting offsets), remaining functionality in
common.ld.

7526a1fd0c app_main: Refactor to use uart.h functions instead of raw register access 
This removes the automatic insertion of CR ahead of LF by the SDK putc
function when called inside the SDK (although we'd already replaced
printf, so most were bypassing this putc function anyhow.)

cc20f8efca NMIExceptionHandler: Don't save callee-saved registers, fix stack alignment 
NMI routine sdk_wDev_ProcessFiq seems to be written in C, meets ABI
calling conventions for callee-saved registers. Not sure why SDK
handlers saved them.

NMI handler now also meets the ABI requirement that stack is 16 byte
aligned (doesn't seem strictly necessary, but can't hurt.)

23ea182e83 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.
