On SM8250 Iris core requires two power rails to function, MX (for PLLs)
and MMCX (for everything else). The commit fa245b3f06cd ("arm64: dts:
qcom: sm8250: Add venus DT node") added only MX power rail, but,
strangely enough, using MMCX voltage levels.
Add MMCX domain together with the (more correct) MX OPP levels.
Fixes: fa245b3f06cd ("arm64: dts: qcom: sm8250: Add venus DT node")
