CHERRY-PICK: lm4: Modified clock gating to allow easy expansion to low power.
Created a new function to enable or disable clocks to various
peripherals. This new function makes it easy to specify if you
want the clock enabled in run mode, sleep mode, and/or deep
sleep mode.
Added infrastructure to specify which GPIOs should interrupt the
EC from deep sleep.
BUG=chrome-os-partner:25661
BRANCH=none
TEST=Passes all unit tests. Ran on a peppy and verified that
the clock gate control registers in run mode (LM4_RCGC regs)
were the same before and after this change.
