drm/imx: Add drm_panic support
Add support for the drm_panic module, which displays a user-friendly
message to the screen when a kernel panic occurs.
v7:
* use drm_panic_gem_get_scanout_buffer() helper
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
