Add support for the drm_panic module, which displays a user-friendly

v8:
 * Replace get_scanout_buffer() logic with drm_panic_set_buffer()

v9:
 * Revert to using get_scanout_buffer() (Sima)
 * move get_scanout_buffer() to plane helper functions

v12:
 * Rename drm_panic_gem_get_scanout_buffer to drm_fb_dma_get_scanout_buffer

4b6cb2b67d drm/imx: move IPUv3 driver into separate subdirectory 
The IPUv3 and DCSS driver are two totally separate DRM drivers. Having
one of them live in the drivers/gpu/drm/imx toplevel directory and the
other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver
into its own subdirectory to make the separation more clear.
