Pali Rohár 1326b49636 PCI: aardvark: Add support for AER registers on emulated bridge 
Aardvark controller supports Advanced Error Reporting configuration
registers.

Export these registers on the emulated root bridge via new .read_ext() and
.write_ext() methods.

Note that in the Advanced Error Reporting Capability header the offset to
the next Extended Capability header is set, but it is not documented in
Armada 3700 Functional Specification. Since this change adds support only
for Advanced Error Reporting, explicitly clear PCI_EXT_CAP_NEXT bits in AER
capability header.

Now the pcieport driver correctly detects AER support and allows PCIe AER
driver to start receiving ERR interrupts. Kernel log now says:

  pcieport 0000:00:00.0: AER: enabled with IRQ 52
