drm/gud: Map framebuffer BOs with drm_gem_fb_vmap()
Abstract the framebuffer details by mapping its BOs with a call
to drm_gem_fb_vmap(). Unmap with drm_gem_fb_vunmap().
The call to drm_gem_fb_vmap() ensures that all BOs are mapped
correctly. Gud still only supports single-plane formats.
No functional changes.
