[PATCH] drm/bridge: dw_hdmi: adapt to updated bridge API

[Heiko Stübner]

Commits 8eb17f05bc18 ("drm/bridge: do not pass drm_bridge_funcs to
drm_bridge_init") and fbc4572e9c48 ("drm/bridge: make bridge registration
independent of drm flow") changed the bridge API without taking into account
the also newly introduced dw_hdmi bridge.

Therefore adapt the dw_hdmi bridge to the new bridge API.

The bridge struct is already allocated using devm_kzalloc, so the destroy
function can go away completely.
