google/poppy: enable trackpad as wake source
This configures GPP_A23 as a wake source for the trackpad. We also
need to set up GPP_A GPE0_DW0, thus evicting GPP_B. We don't have any
interesting signals in GPP_B, so we won't be missing it.
I don't have hardware with A23 wired up, so i just tested the wake
source using A19 which is essentially identical to A23.
TEST=verified we can trackpad can wake system from suspend
