The desired clock frequency was correctly set to 400MHz in the device tree
but was lowered by the driver to 300MHz breaking 4K 60Hz content playback.
Fix the issue by removing the driver call to clk_set_rate(), which reduce
the amount of board specific code.

I was going to ask whether there might be any device trees without the
assigned-clock-rates around that this patch could break, but the DT
node was introduced with 400 MHz clock setting in the initial commit
dd6dc0c4c126 ("arm64: dts: rockchip: Add AV1 decoder node to rk3588s").
