arcada_ish: hook up 360 hall sensor to ISR
Ensure that 360-degree-hall sensor is hooked up to the tablet mode ISR,
which should in turn ignore any weird lid angle calculations when the
hall sensor is active (i.e. lid is at 360 degrees)
BRANCH=R75
BUG=b:131785573
TEST=arcada does not have spurious edges on the NB_MODE# signal when
the lid is all the way open in 360 degree mode.
