drm/vc4: hdmi: Prevent clock unbalance
commit 5b00600 upstream. Since we fixed the hooks to disable the encoder at boot, we now have an unbalanced clk_disable call at boot since we never enabled them in the first place. Let's mimic the state of the hardware and enable the clocks at boot if the controller is enabled to get the use-count right.
