Split out power button code from switch.c
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.
BUG=chrome-os-partner:18945
BRANCH=none
TEST=manual

2. Press power button at recovery screen turns off.
