mb/google/hatch: Set trackpad irq and wake to GPP_A21
Previously, We had to use GPP_A21 for trackpad wake and GPP_D21 for
trackpad interrupts due to ITSS not honoring the INVERT config. Now
that's fixed, we can configure trackpad wake and interrupts on GPP_A21
only.
BUG=b:130436471
BRANCH=None
TEST=1. boot a hatch device and make sure we can move the cursor with the trackpad
2. Run powerd_dbus_suspend and wake by clicking on the trackpad and ensure
through "mosys eventlog list" that the wake source is the trackpad.\
3. Run "echo mem > /sys/power/state", wait until device goes into S3,
click trackpad to ensure device wakes.
