honeybuns: Add power button support
This CL adds support for the power button including a new task to
allow for power sequencing delays.
The power button is used for two purposes. First, to turn the dock on
or off, and second, to allow for a user set preference of the MF for
DP 2 or 4 lane selection. If the dock is off, the dock will be turned
on as soon as the short press timer expires. If the dock is already
on, then a short press action is only recognized on the release so a
long press will only change the MF preference.
BUG=b:164157329
BRANCH=quiche
TEST=manaual
short press -> turns dock on off as expected
long press -> toggles MF preference and flashes LED
