mb/google/brya/var/nivviks: Implement WWAN power sequencing
Nissa is using the FM101, which has the following power sequencing
requirements:
Power on: assert WWAN_EN, delay 20 ms, deassert WWAN_RST_L
Power off: assert WWAN_RST_L, delay 20 ms, deassert WWAN_EN
Add a power resource to the USB device, and use wwan_power.asl to
handle the power off sequence.
