Public bug reported:
[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.
