[PATCH 1/2] drm/rockchip: create the fake mmap offset during gem creation

[Heiko Stuebner]

Similarly to the equivalent exynos-fix in commit 48cf53f4343a
("drm/exynos: create a fake mmap offset with gem creation") the rockchip
drm driver also calls the drm_gem_create_mmap_offset fake-offset creation
on every invocation of rockchip_gem_dumb_map_offset.

Move that to the creation of the gem to only create that offset once.
