mb/google/skyrim: Update ASPM settings for the NVMe device
This enables L1.2 for the SSD port.
link_hotplug is unused on Mendocino, so remove it while I'm here, just
as code cleanup. This has no functional difference.
Enabling L1.2 on other devices currently causes problems. Debug is
ongoing.
BUG=b:265890321
TEST=Build & boot, look at states enabled in lspci. Test device
functionality.
