mainboard/google/skyrim/baseboard: Enable Wake-On-LAN functionality

The generic wifi driver currently contains a lot of intel-specific
functionality that interferes with enabling wake-on-lan. This commit
changes the device tree to use the generic PCIe driver which better
supports this functionality.

BUG=b:237682766
TEST=Booted on skyrim device and verified that wake on LAN works
