[PATCH] drm: Update drm_cache.c to pull in the new drm_cache.h

[Chris Wilson]

The prototypes were moved to a new header, but the function definitions
were not updated to pull in the declarations.

drivers/gpu/drm/drm_cache.c:79:1: warning: no previous prototype for ‘drm_clflush_pages’ [-Wmissing-prototypes]
drivers/gpu/drm/drm_cache.c:120:1: warning: no previous prototype for ‘drm_clflush_sg’ [-Wmissing-prototypes]
drivers/gpu/drm/drm_cache.c:152:1: warning: no previous prototype for ‘drm_clflush_virt_range’ [-Wmissing-prototypes]

Fixes: f9a87bd7d5b6 ("drm: Move drm_clflush prototypes to drm_cache header file")
