The RK3582 SoC is a variant of the RK3588S with some IP blocks disabled.
What blocks are disabled/non-working is indicated by ip-state in OTP.
This add initial support for RK3582 by using ft_system_setup() to mark
any cpu and/or vdec/venc node with status=fail as indicated by ip-state.
This apply same policy as vendor U-Boot for RK3582, i.e. two big cpu
cores and one vdec/venc core is always failed/disabled.
Enable Kconfig option OF_SYSTEM_SETUP in board defconfig to make use of
the required DT fixups for RK3582 board variants.

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.
Isn't the GPU supposed to be possibly non-fonctional on RK3582/RK3583?
If we don't disable it in the DT, how will the system actually behave?
@Kever may have more official info on that?
See remarks on v2 otherwise, most of them still apply.
- Update rkvdec node name to match latest mainling Linux DT patches.
Should we rather wait for the patches to be actually merged before
trying to patch the device tree nodes that do not exist yet?
Cheers,
Quentin
