Subject: [PATCH 8/8] arm64: dts: qcom: sm8250: correct frequencies in the
 Iris OPP table

The OPP table for the Iris core is wrong, it copies the VDD table from
the downstream kernel, but that table is written for the
video_cc_mvs0_clk_src, while the upstream uses video_cc_mvs0_clk for OPP
rate setting (which is clk_src divided by 3). Specify correct
frequencies in the OPP table.

Fixes: fa245b3f06cd ("arm64: dts: qcom: sm8250: Add venus DT node")
