[PATCH 2/7] drm: verisilicon: stop using deprecated devm_drm_of_get_bridge()

[Luca Ceresoli]

devm_drm_of_get_bridge() is deprecated, switch to
of_drm_get_bridge_by_endpoint(). As of_drm_get_bridge_by_endpoint() returns
a refcounted bridge, ensure it is put by using bridge.next_bridge.

Fixes build failure when CONFIG_OF is disabled.

Fixes: aa8a8c7e4641 ("drm/bridge: panel: move all code to drm_panel.c")
