drm: add helper to get crtc timings (v5)
We need to get hdisplay and vdisplay in a few places so create a
helper to make our job easier.
Note that drm_crtc_check_viewport() and intel_modeset_pipe_config() were
previously making adjustments for doublescan modes and vscan > 1 modes,
which was incorrect. Using our new helper fixes this mistake.
v2 (by Matt): Use new stereo doubling function (suggested by Ville)
v3 (by Matt):
- Add missing kerneldoc (Daniel)
- Use drm_mode_copy() (Jani)
v4 (by Matt):
- Drop stereo doubling function again; add 'stereo only' flag
to drm_mode_set_crtcinfo() instead (Ville)
v5 (by Matt):
- Note behavioral change in drm_crtc_check_viewport() and
intel_modeset_pipe_config(). (Ander)
- Describe new adjustment flags in drm_mode_set_crtcinfo()'s
kerneldoc. (Ander)
