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

Meanwhile, the virt SPCR golden reference files have been updated to
accommodate the SPCR Table version 4.

This patch series depends on Sunil's patch series [3], where Bios-Table-Test
is now supported by both ARM and RISC-V.

Changes in v2:
- Utilizes a three-patch approach to modify the ACPI pre-built binary
  files required by the Bios-Table-Test.
- Rebases and incorporates changes to support both ARM and RISC-V ACPI
  pre-built binary files.
