[PATCH v2 3/6] drm/imx/dw-hdmi: convert to of_drm_find_and_get_bridge()

[Luca Ceresoli]

of_drm_find_bridge() is deprecated. Move to its replacement
of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it
is put when done.

Signed-off-by: Luca Ceresoli <luca.ceresoli@xxxxxxxxxxx>

Changes  in v2:
- add missing drm_bridge_put() on component_add() failure
- reorder lines in dw_hdmi_imx_remove()
