drm/vc4: hdmi: Switch to blank pixels when disabled
In order to avoid pixels getting stuck in an unflushable FIFO, we need when
we disable the HDMI controller to switch away from getting our pixels from
the pixelvalve and instead use blank pixels, and switch back to the
pixelvalve when we enable the HDMI controller.
