mb/google/hatch: Enable wake from trackpad
For some reason, wake does not currently work from GPP_D21, but IRQs
are working fine from that gpio. Thus, we have to switch IRQ to
GPP_D21 and wake to GPP_A21, which was previously used for IRQs from
the trackpad. Additionally, we need to use two gpios for irqs and
wake source at the moment because of b:123967687, where FSP is locking
down PCR and configuring ITSS. We need to configure the wake source
gpio as inverted and the IRQ gpio as non-inverted until the bug is
resolved.
BUG=b:121212459
BRANCH=None
TEST=run evtest with trackpad
Use trackpad with ChromeOS UI and make sure it reacts as expected.
Run powerd_dbus_suspend and press trackpad and make sure DUT
wakes.
