drm/atomic: Convert drm_atomic_get_plane_state() to use new plane state

Browse Source 
The drm_atomic_get_plane_state() function calls the deprecated
drm_atomic_get_existing_plane_state() helper to get find if a plane
state had already been allocated and was part of the given
drm_atomic_state.

At the point in time where drm_atomic_get_plane_state() can be called
(ie, during atomic_check), the existing state is the new state and
drm_atomic_get_existing_plane_state() can thus be replaced by
drm_atomic_get_new_plane_state().
