Subject: drm/gma500: Use to_gtt_range() everywhere
Git-commit: 9f40dbd4416f14657d9b354b7ec855244d97a91c
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Convert upcasts from struct drm_gem_object to struct gtt_range to
to_gtt_range(). Some places used container_of() directly.
