From: Bharat Gooty <bharat.gooty@xxxxxxxxxxxx>
Declare the full size array for all revisions of PAX register sets
to avoid potentially out of bound access of the register array
when they are being initialized in iproc_pcie_rev_init().
Fixes: 06324ede76cdf ("PCI: iproc: Improve core register population")
