[PATCH 1/1] Platform/RaspberryPi: Update ACPI table revision

["Sunny Wang" <Sunny.Wang@arm.com>]

As per ACPI 6.3 specification, the DSDT/SSDT table should use revision 2
, so update the revision numbers to 2.
This also fixes https://github.com/pftf/RPi4/issues/94 (FWTS failures).

Testing Done:
  - Booted to UEFI Shell and used apciview command to check all ACPI
    tables' revision.
  - Ran FWTS test and no longer see the ACPI DSDT and SSDT revision
    failures. Note that the XSDT revision failure is caused by the FWTS
    tool's issue that got fixed in
    commit c522bfedc9839a474b8d590ba36bec77436d2e90
