zynqmp: Ignore the revision field of the IDCODE
The revision field may change between silicon revisions without changing
the mapping to a part. This avoids errors like:
ERROR: Incorrect XILINX IDCODE 0x14738093, maskid 0x4600093
NOTICE: ATF running on XCZUUNKN/EP108 v3/RTL5.1 at 0xfffe5000
on parts with a newer revision.
