drm/bridge: analogix_dp: inline analogix_dp_prepare_panel()

Browse Source 
The analogix_dp_prepare_panel() is now only calling a corresponding
drm_panel function. Inline it to simplify the code.

* If @prepare is true, this function will prepare the panel. Conversely, if it

* The function will disregard the current state
