[PATCH] drm/fb_dma: s/drm_panic_gem_get_scanout_buffer/drm_fb_dma_get_scanout_buffer

[Maíra Canal <mcanal@xxxxxxxxxx>]

On version 11, Thomas suggested to change the name of the function and
this request was applied on version 12, which is the version that
landed. Although the name of the function changed on the C file, it
didn't changed on the header file, leading to a compilation error as
such:

drivers/gpu/drm/imx/ipuv3/ipuv3-plane.c:780:24: error: use of undeclared
identifier 'drm_fb_dma_get_scanout_buffer'; did you mean 'drm_panic_gem_get_scanout_buffer'?
  780 |         .get_scanout_buffer = drm_fb_dma_get_scanout_buffer,
      |                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                               drm_panic_gem_get_scanout_buffer
./include/drm/drm_fb_dma_helper.h:23:5: note: 'drm_panic_gem_get_scanout_buffer'
declared here
   23 | int drm_panic_gem_get_scanout_buffer(struct drm_plane *plane,
      |     ^
1 error generated.
