[SRU] [Unstable/OEM-5.14] [PATCH 0/1] Let VMD follow host bridge PCIe settings

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1954611

[Impact]
Some platforms have endless AER message floods kernel log, slows done
disk I/O.

[Fix]
Honor BIOS settings to disable AER for Intel VMD.

[Test]
Use dmesg to check kernel log, no more AER message since AER is
disabled.

[Where problem could occur]
The patch copies PCIe settings from host bridge, so some PCIe features
will be disabled as a result. This may not be desirable for some users.
