Kevin O'Connor 9a11286327 stm32: Implement armcm_main() in arch specific code 
Move armcm_main() to stm32f0.c, stm32f1.c, and stm32f4.c.  This gives
the arch specific code more control on the early boot setup.

Kevin O'Connor faeaa54925 armcm_boot: Use armcm_main() instead of main() to start board code 
The main() function has a special meaning to gcc and using it can
result in different code generation.  Use armcm_main() to avoid that.

Also, invoke SystemInit() from the board specific armcm_main() code.
This gives the board code more control over board initialization.

external crystal is requested (instead use the PLL synced to the
external 32Khz signal).

Kevin O'Connor 7a32860455 atsamd: Increase ADC frequency on SAMD51 
The SAMD51 ADC is only clocked on rising edges (vs both rising and
falling edges on the SAMD21) and it has a greater minimum frequency
than the SAMD21.  So, increase the ADC clock.
