rambi: use SERIRQ pad as keyboard irq in gpio mode
The level shifting between 3.3V and 1.8V for the SERIRQ
signal is not working. Instead use the SERIRQ pad as
a gpio which is used as a direct IRQ signal for the
keyboard interupt.
BUG=chrome-os-partner:23965
BRANCH=None
TEST=Built and booted rambi. Keyboard works with associated EC change.
