[PATCH 1/4] drm/vc4: hdmi: Mark the device as active if running

[Maxime Ripard <maxime@cerno.tech>]

If we detect the device as running we make sure we get the reference
count right for clocks, but we don't do as such for the runtime PM
count, let's call pm_runtime_enable to make sure it's accurate.

Fixes: 5b0060004236 ("drm/vc4: hdmi: Prevent clock unbalance")
