Francesco Valla	095232711f	drm/draw: fix color truncation in drm_draw_fill24 ... The color parameter passed to drm_draw_fill24() was truncated to 16 bits, leading to an incorrect color drawn to the target iosys_map. Fix this behavior, widening the parameter to 32 bits.

Jocelyn Falempe	31fa2c1ca0	drm/panic: Move drawing functions to drm_draw ...
