[PATCH 6.12 257/322] drm/panic: Move drawing functions to drm_draw

6.12-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jocelyn Falempe jfalempe@redhat.com

[ Upstream commit 31fa2c1ca0b239f64eaf682f1685bbbd74fc0181 ]

Move the color conversions, blit and fill functions to drm_draw.c, so that they can be re-used by drm_log. drm_draw is internal to the drm subsystem, and shouldn't be used by gpu drivers.
