[PATCH 07/14] drm/bridge: dw-hdmi: Commonize dw_hdmi_connector_create()

[Cristian Ciocaltea]

In preparation to add support for the HDMI 2.1 Quad-Pixel TX Controller
and minimize code duplication, export dw_hdmi_connector_create()
function, while adding a new parameter to allow using a different
drm_connector_funcs structure.
