[PATCH 4/6] MIPS: OCTEON: Remove redundant enable of COR/UNCOR error

From: Naveen Naidu
Date: Mon Oct 04 2021 - 14:02:35 EST


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, correctable/uncorrectable errors
are enabled by set_device_error_reporting() in the aer_probe()
path.

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