Subject: [PATCH v5 38/80] drm/vc4: hdmi: Use debugfs private field

We're calling vc4_debugfs_add_file with our struct vc4_hdmi pointer set
in the private field, but we don't use that field and go through the
main struct vc4_dev to get it.

Let's use the private field directly, that will save us some trouble
later on.
