Implement mmap via struct drm_gem_object_functions.mmap for amdgpu, radeon and nouveau. This allows for using common DRM helpers for the mmap-related callbacks in struct file_operations and struct drm_driver. The drivers have their own vm_ops, which are now set automatically by the DRM core functions. The code in each driver's verify_access becomes part of the driver's new mmap implementation. With the GEM drivers converted, vmwgfx is the only user of ttm_bo_mmap() and related infrastructure. So move everything into vmwgfx and delete the rsp code from TTM. This touches several drivers. Preferably everything would be merged at once via drm-misc-next.
