[PATCH v15 04/19] drm/etnaviv: Make etnaviv_gem_prime_vmap() a static function

[Sui Jingfeng]

The etnaviv_gem_prime_vmap() function has no caller in the
etnaviv_gem_prime.c file, move it into etnaviv_gem.c file.
While at it, rename it as etnaviv_gem_object_vmap(), since
it is a intermidiate layer function, it has no direct relation
ship with the PRIME. The etnaviv_gem_prime.c file already has
etnaviv_gem_prime_vmap_impl() as the implementation to vmap
a imported GEM buffer object.
