The comment in the DT mentions that "currently it is not possible to let
display clocks configure automatically, so we need to set them manually".

Since commit ff06ea04e4cf ("clk: imx: clk-imx8mp: Allow media_disp pixel
clock reconfigure parent rate"), this is no longer the case.

Make use of this new functionality by dropping the now unneeded
assigned-clock-rates in &media_blk_ctrl.
