        AMD Inagua: PlatformGnbPcie.c: Allocate exact needed size for buffer

        Reviewed-on: http://review.coreboot.org/3246

changed one calculation for the size of the array PortList[] to
reflect only four elements, but neglected three additional calculations
of the size of the same table.

Correct that by setting the size for four array elements in all four
calculations.
