This series add initial support for RK3582 support. The RK3582 is a
variant of the RK3588S with a few ip blocks disabled. What blocks are
disabled/non-working is indicated by the ip-state in OTP.
Compared to the vendor U-Boot variant, this mark cpu and gpu with
status=fail instead of removing nodes during DT fixup. Linux skip cpu
cores marked as failed staring from v5.17-rc1, however the GIC driver
will generate a harmless WARN_ON that safely can be ignored. A patch for
Linux will be sent to skip the WARN_ON for failed/disabled cpu cores.
Changes in v2:
- Refactor code to first apply policy to ip-state and then fail cores
based on the updated ip-state
- Add support for failing rkvdec and rkvenc cores
- Append soc compatible to board model
- Add patch to add support for ROCK 5C Lite variant
