drm/debugfs: Move HDMI debugfs registration to state helper

Browse source

The HDMI debugfs files are only useful for connectors that already make
use of the HDMI state helpers. In addition, relying on HDMI-specific
functions in drm_debugfs.c can lead to circular linking problems later
down the line.

Move hdmi_debugfs_add() and friends to a new helper in
drm_hdmi_state_helper.c, and make all current users (vc4, sun4i, bridge)
either use it as a debugfs_init func, or call it directly in its
debugfs_init func.
