[PATCH] drm: Make drm_clflush_virt_range() void*

[ville.syrj...@linux.intel.com]

From: Ville Syrj?l? <ville.syrj...@linux.intel.com>

Currently drm_cflush_virt_rage() takes a char* so the caller probably
has to do pointless casting to avoid compiler warnings. Make the
argument void* instead to avoid such issues.
