drm: Include <video/cmdline.h> for mode parsing

Include <video/cmdline.h> in drm_connector.c to get video_get_options()
and avoid the dependency on <linux/fb.h>. The replaced function
fb_get_options() is just a tiny wrapper around video_get_opions(). No
functional changes.

Include <linux/property.h> to get fwnode_handle_put(), which had been
provided via <linux/fb.h>.
