drm: drm_err: Remove unnecessary __func__ argument

Browse Source 
Removing the unnecessary drm_err __func__ argument by using
the equivalent %pf and __builtin_return_address(0) makes the
code smaller for every use of the DRM_ERROR macro.

For instance: (allmodconfig)

$ size drivers/gpu/drm/i915/i915.o*
   text	   data	    bss	    dec	    hex	filename
