drm/exynos: Remove empty exynos_drm_gem_prime_{vmap,vunmap}()

Browse Source 
The functions exynos_drm_gem_prime_{vmap,vunmap}() are empty. Remove
them before changing the interface to use struct drm_buf_map. As a side
effect of removing drm_gem_prime_vmap(), the error code changes from
ENOMEM to EOPNOTSUPP.
