drm/bridge: panel: move prepare_prev_first handling to drm_panel_bridge_add_typed
The commit 5ea6b1702781 ("drm/panel: Add prepare_prev_first flag to
drm_panel") and commit 0974687a19c3 ("drm/bridge: panel: Set
pre_enable_prev_first from drmm_panel_bridge_add") added handling of
panel's prepare_prev_first to devm_panel_bridge_add() and
drmm_panel_bridge_add(). However if the driver calls
drm_panel_bridge_add_typed() directly, then the flag won't be handled
and thus the drm_bridge.pre_enable_prev_first will not be set.
Move prepare_prev_first handling to the drm_panel_bridge_add_typed() so
that there is no way to miss the flag.
