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.
