Bug description:
[Impact]
Errors like Master Abort can be flagged before setting up PCI devices.
[Fix]
Clear PCI status that BIOS handed over to the OS.
[Test]
Using `lspci`, no more errors after boot.
[Where problems could occur]
If there's any driver's probe routine depends on PCI status to have
different behavior, this can cause some cracks. There doesn't seem to be
any driver doing such insane thing though.
