b6325f4099 drm: etnaviv: clean up vram_mapping submission/retire path 
Currently, we scan the list of mappings each time we want to operate on
the vram_mapping struct.  Rather than repeatedly scanning these, look
them up once in the submission path, and then use _reference and
_unreference methods as necessary to manage this object.

ce3088fdb5 drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmap 
This function follows the semantics of vmap() by returning
NULL in case of an error. To make things less confusing
rename it to make make both functions more closely related.
