lpc: Clean up processing wake events

Every board other than link does the same thing - filter out the power
button event, then set the WAKE_L gpio level based on the remaining
events.  This code doesn't need to be duplicated 7 times, so make it common.

Link didn't filter out the power button wake signal, but works fine
with the common implementation.  Like the other boards it gets a power
button wake event via the dedicated PCH PWRBTN# signal.

BUG=chrome-os-partner:18343
BRANCH=none
TEST=suspend link, then wake using power button press
     compile all platforms; pass unit tests
