Bug description:
[Impact]
ASPM of NVMe behind VMD is not enabled when BIOS FADT doesn't allow ASPM to
be modified.
That causes higher overall power consumption.
[Fix]
Allow ASPM to be enabled.
While at this, remove old cruft that can interfere upstream VMD driver.
[Test]
Check the value of `/sys/kernel/debug/pmc_core/slp_s0_residency_usec`. Now
system can reach deepest power saving state during sleep.
[Where problems could occur]
Some NVMe may have I/O issue when ASPM is enabled. But for this scenario the
issue will also appear when VMD is disabled.
