mb/google/brya: Set WWAN_PCIE_WAKE_ODL as interrupt on Redrix

Browse Source 
This signal gets deasserted by the WWAN modem to reactivate the PCIe
link when in low power mode. In order to handle this efficiently, the
kernel needs to set up an interrupt.

BUG=b:301150499
TEST=Compiled and tested on google/redrix
