drm: mali-dp: Remove mclk rate management
The rate of mclk depends on the use-case. If no downscaling is required, then mclk == pxlclk is a valid option; with downscaling however, the rate at which mclk runs determines how much a plane can be downscaled before composition. This is a system integration + power management issue that is more suited to firmware rather than this driver.
