As pointed out by Konrad during the review of SM8350 / SC8280XP
patchset, Iris aka Venus description has several flows. It doesn't scale
MMCX, the frequencies in the OPP table are wrong, etc.
Let's correct the Iris/Venus enablement for SM8250 (unfortunately also
stopping it from being overclocked).
The videocc patches (DT, DTS) can be applied during -rc, the rest of the
patches should go for the next -rc1.
