mb/google/drallion: Set touchpad IRQs as wake source

Browse Source 
Elan touchpad driver in newer linux kernels (>= 5.15) no longer
explicitly configures the touchpad as a wakeup source for devices
not using device tree. It is now assumed this information should be
extracted from ACPI, therefore we need to update drallion's devicetree
so that the device regains its lost capability.

TEST=update drallion FW and verify touchpad can cause wake up from
     suspend
