mb/google/skyrim: Enable L1 ASPM substates for PCIe devices
Enable both L1.1 and L1.2 substates for the WiFi, SD card reader,
and SSD (both NVMe and eMMC). If a given device does not support
a particular substate, then it will not be enabled during PCIe
enumeration by coreboot.
BUG=b:270690572
TEST=build/boot multiple skyrim/whiterun/frostflow SKUs with different
storage configs, verify WiFi/SD card/SSD all functional and have L1
substates enabled insofar as they are supported by the device.
BRANCH=skyrim
