[L/M/Unstable] [PATCH 9/9] UBUNTU: SAUCE: PCI: vmd: Mark ASPM override for device behind VMD bridge

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/2034504

pci_enable_link_state() doesn't enable ASPM when ACPI_FADT_NO_ASPM is
set.

So allow ASPM can truly be enabled to make vmd_pm_enable_quirk() work as
intended.
