sunxi: display: use common video_ctfb_mode_to_display_timing()

Since video_ctfb_mode_to_display_timing() has been implemented by moving
sunxi_ctfb_mode_to_display_timing() to video_modes.c and it's meant to be
used by other video subsystem, let's use it instead of local
sunxi_ctfb_mode_to_display_timing().
