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
