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, root port's error reporting is
enabled by aer_enable_rootport() in the aer_probe() path.

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