drm/fb_dma: Add generic get_scanout_buffer() for drm_panic
This was initialy done for imx6, but should work on most drivers
using drm_fb_dma_helper.
v8:
* Replace get_scanout_buffer() logic with drm_panic_set_buffer()
(Thomas Zimmermann)
v9:
* go back to get_scanout_buffer()
* move get_scanout_buffer() to plane helper functions
v12:
* Rename drm_panic_gem_get_scanout_buffer to drm_fb_dma_get_scanout_buffer
(Thomas Zimmermann)
* Remove the #ifdef CONFIG_DRM_PANIC, and build it unconditionnaly, as
it's a small function. (Thomas Zimmermann)
