rambi: use gpio for keyboard irq
The rambi board has issues using the SERIRQ method
for triggering the keyboard IRQ. Namely, the current
level-shifter in place for the bidrectional SERIRQ
signal introduces delay resulting in the SERIRQ
being out of phase with the clock. Moreover, there
appears to be a mismatch of expectations with the
number of start frames on the SEIRQ line. Bay Trail
uses a fixed 8 while the TI docs suggest it only
supports 6.
BUG=chrome-os-partner:23965
BRANCH=None
TEST=Built and booted rambi with keyboard working in
kernel with interrupts.
