drm/ssd130x: Use shadow-buffer helpers when managing plane's state

Browse source

The commit 45b58669e5 ("drm/ssd130x: Allocate buffer in the plane's
.atomic_check() callback") moved the buffers allocation to be done in
the primary plane's .atomic_check() callback.

But it missed that since the driver uses a shadow-buffered plane, the
__drm_gem_{reset,duplicate,destroy}_shadow_plane() helper functions
must be used in the struct drm_plane_funcs handlers.

This was missed because the mentioned commit did not remove the macro
DRM_GEM_SHADOW_PLANE_FUNCS, which leads to the custom plane's atomic
state management handlers to not be used.
