Randall Spangler 45bc5c1a21 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

1. Power+refresh+esc goes to recovery mode,
2. Press power button at recovery screen turns off.
3. With system off, power button turns system on.
4. Press power button for a second; screen locks.
5. Press power button while typing; blocks keystrokes while it's pressed.
6. Hold power button down for 8 sec; system forced to shutdown.
7. From EC console, with system on:
   hostevent clear
   hostevent -> event 0x04 is clear
   press power button
   hostevent -> event 0x04 is set
8. From EC console, with system off:
   powerbtn -> system turns on
   powerbtn 5000 -> system turns off, just like power button was held for 5 sec
