[PATCH 4/4] Revert "drm/vc4: hdmi: Enforce the minimum rate at runtime_resume"

[Maxime Ripard]

This reverts commit ae71ab585c819f83aec84f91eb01157a90552ef2.

Commit ae71ab585c81 ("drm/vc4: hdmi: Enforce the minimum rate at
runtime_resume") was introduced to work around an issue partly due to
the clk-bcm2835 driver on the RaspberryPi0-3.

Since we're not using that driver for our HDMI clocks, we can now revert
it.
