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.

Kevin O'Connor a46244057c stm32: Support 16bit packet memory access on usbfs controller
The stm32f0 line uses 16bit packet memory reads/writes (as opposed to
the goofy 32bit accesses required on the stm32f103).

Kevin O'Connor bbf6f87de0 avr: List 20Mhz option below 16Mhz option in Kconfig
When enabling "low level options" in Kconfig, selecting a chip that is

is the preferred default, so list that first in the menu.
