edac/85xx: Disable invalid PEX_CONFIG_ADDR/PEX_CONFIG_DATA access enable bit
When kernel PCIe bus code to initialize and configure these PCIe devices
on booting will use some invalid PEX_CONFIG_ADDR/PEX_CONFIG_DATA, edac
driver prints the much notice information as the following:
PCIE error(s) detected
PCIE ERR_DR register: 0x00020000
PCIE ERR_CAP_STAT register: 0x80000001
PCIE ERR_CAP_R0 register: 0x00000800
PCIE ERR_CAP_R1 register: 0x00000000
PCIE ERR_CAP_R2 register: 0x00000000
PCIE ERR_CAP_R3 register: 0x00000000
So disable the invalid PEX_CONFIG_ADDR/PEX_CONFIG_DATA access interrupt
generation enable bit and invalid PEX_CONFIG_ADDR/PEX_CONFIG_DATA access
detection enable bit to fix ugly print.
