References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.
No functional changes as the code already uses crtc_state->mode
to populate the clip, which is also what drm_mode_get_hv_timing()
uses.
Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().
v2: Rebase due to tegra_plane_state_add() relocating to plane.c
