Currently, the PCIe AER subsystem does not enable AER in the PCIe
Endpoints via the Device Control register. It's only done for the
Root Port and all PCIe Ports in between the Root Port and the
Endpoint(s). Some device drivers enable AER in their PCIe device by
directly calling pci_enable_pcie_error_reporting(). But in most
cases, AER is currently disabled in the PCIe Endpoints.
This patch enables AER on PCIe Endpoints now as well in
set_device_error_reporting(). This will make the ad-hoc calls to
pci_enable_pcie_error_reporting() superfluous.
