mb/google/brya/variants/felwinter: Fix stylus UI behavior bug

Fix stylus UI behavior bug.
1) it appears the kernel's gpio_key driver is not expecting
an IRQ descriptor for the `gpio` property, therefore change
to an active-low input.
2) The wakeup event was configured backwards.

Change list
- Configure GPP_A7 as "ACPI_GPIO_INPUT_ACTIVE_LOW".
- Change wakeup_event_action from ASSERTED to DEASSERTED.
