Update the SPCR table to accommodate the SPCR Table revision 4 [1].
The SPCR table has been modified to adhere to the revision 4 format [2].

Meanwhile, the virt SPCR golden reference file for RISC-V have been updated to
accommodate the SPCR Table revision 4.

Changes in v5:
- Reverted the SPCR table revision history for the ARM architecture.
- Corrected the output of the SPCR Table diff.

Changes in v4:
- Remove the SPCR table revision 4 update for the ARM architecture.

Changes in v3:
- Rebased on the latest QEMU.
- Added Acked-by: Alistair Francis <alistair.francis@wdc.com>

Changes in v2:

  pre-built binary files.
