The power button code is platform-independent. This change splits the
code out of the LM4 switch.c module so that a subseqent change to
STM32 platforms can start using it.

This is part one of a series to merge the keyboard scan interface to
be common across all platforms.

read code, and sets up protocol-specific CONFIG options. It makes the
next CL which actually merges keyboard scanning easier to parse.
