PCI/AER: Enable error reporting when AER is native
If we have native control of AER, set the following error reporting enable
bits:
- Correctable Error Reporting Enable
- Non-Fatal Error Reporting Enable
- Fatal Error Reporting Enable
- Unsupported Request Reporting Enable
Note that these bits are all in the Device Control register and are not
AER-specific.
This affects all devices with an AER capability, including hot-added
devices.
Please note that this change is quite invasive, as error reporting now will
be enabled for all available PCIe Endpoints, which was previously not the
case.
When "pci=noaer" is selected, error reporting stays disabled of course.
[bhelgaas: commit log, note error reporting is not AER-specific]
