This driver obtains a bridge pointer from of_drm_find_bridge() in the probe
function and stores it until driver removal. of_drm_find_bridge() is
deprecated. Move to devm_of_drm_get_bridge() which puts the bridge
reference on remove or on probe failure.

Note: this driver stores the bridge pointer in the adv_bridge global
variable, which could hold a value from a previous probe. However the code
flow always sets the adv_bridge value in the probe function before it is
read, so the change is safe.
