[PATCH v4 0/3] rockchip: Add initial RK3582 support

[Jonas Karlman]

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, the gpu and
vdec/venc 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 once this lands.

It is recommended to use rk3588_ddr_lp4_1848MHz_lp5_2112MHz_v1.19.bin
as DRAM init blob RK3582, listed in latest RKBOOT/RK3582MINIALL.ini.

Changes in v4:
- Update policy to always fail gpu for RK3582
- Drop code and comment related to RK3583
- Update rkvdec node name to match latest mainline Linux DT patches
- Update commit message to reflect updated policy

Changes in v3:
- Apply same policy for RK3582/RK3583 to match vendor U-Boot
  linux-6.1-stan-rkr6 tag, allow use of the GPU and one vdec core.
- Update rkvdec node name to match latest mainline Linux DT patches.
- Update commit message to reflect updated policy

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
