Subject: [v1] arm64/dts/qcom/sc7280: update mdp clk to max supported value to support higher refresh rates

Panels with higher refresh rate will need mdp clk above 300Mhz.
Select max frequency for mdp clock during bootup, dpu driver will
scale down the clock as per usecase when first update from the framework is received.
