mb/google/hatch: Remove GPIO_DRIVER from pen eject GPIO configuration
A closer read of the EDS indicates that when GPIO Driver mode is
selected, GPIO input event updates are limited to GPI_STS only.
GPI_GPE_STS updates are therefore masked, and we don't want to enable
this behavior. It masks the GPE and does not allow us to see this GPE
as a wake source, obscuring the reason that the system woke up.
Also switch the IRQ from level-triggered to edge-triggered,
otherwise the system will auto-wake from any sleep state when the
pen is ejected from the garage.
BUG=b:132981083
BRANCH=none
TEST=Wake up system from S0ix using pen eject, verify that mosys
eventlog shows GPE#8 as the S0ix wakeup source. Wake up system from S3
via pen eject, and verify that the wakeup source shows as GPE#8.
