Subject: [PATCH 3/6] MIPS: OCTEON: Remove redundant enable of PCIe normal error reporting

e8635b484f64 ("MIPS: Add Cavium OCTEON PCI support.") added MIPS
specific code to enable PCIe and AER error reporting (*irrespective
of CONFIG_PCIEAER value*) because PCI core didn't do that at the time.

Currently when CONFIG_PCIEAER=y, the PCIe normal error reporting is
enabled by pci_enable_pcie_error_reporting() in the aer_probe() path.

It is now no longer necessary for Octeon code to enable PCIe normal
error since it's done when PCIe bus loads the AER service driver.
