[PATCH] drm/ssd130x: drop DRM_GEM_SHADOW_PLANE_FUNCS override

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

It is not possible for ssd130x_primary_plane_funcs to use both
its own reset/duplicate/destroy callbacks and the ones from
DRM_GEM_SHADOW_PLANE_FUNCS:

In file included from drivers/gpu/drm/solomon/ssd130x.c:29:
include/drm/drm_gem_atomic_helper.h:100:18: error: initialized field overwritten [-Werror=override-init]
  100 |         .reset = drm_gem_reset_shadow_plane, \
  101 |         .atomic_duplicate_state = drm_gem_duplicate_shadow_plane_state, \
  102 |         .atomic_destroy_state = drm_gem_destroy_shadow_plane_state
      |                  ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/solomon/ssd130x.c:744:9: note: in expansion of macro 'DRM_GEM_SHADOW_PLANE_FUNCS'
  744 |         DRM_GEM_SHADOW_PLANE_FUNCS,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~

Since the custom callbacks were just added, I assume these are the
ones it is meant to use, so remvoe the generic overrides.
