BUG=chrome-os-partner:24912
BRANCH=baytrail
TEST=Manual. Enable CONFIG_POWER_BUTTON_IGNORE_LID
on a device, boot it, and go into dock mode with
external monitor attached. Fake-close the lid with a
magnet or servo. Verify the power button still sends
press/release events to the host with evtest.

If the power button is pressed for a shorter period than the debounce
timeout, then the debounced state never changes. This was causing the
power button state machine to disable scanning (in the interrupt
handler) but never re-enable it (in the deferred handler).
Easy fix; just re-enable based on whether the current state is
released, not whether the debounced state is transitioning to
released.

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.
