drm/i915/display: Allow fastset for change in HDR infoframe
Changes in Dynamic Range and Mastering infoframe
should not trigger a full modeset. Therefore, allow
fastset. DP SDP programming is already hooked up in the
fastset flow but HDMI AVI infoframe update is not, add it.
Any other infoframe that can be fastset should be added to
the helper intel_hdmi_fastset_infoframes().
v3:
- Create a wrapper intel_ddi_update_pipe_hdmi to stick to
uniform naming (Jani)
- Do not disable HDMI AVI infoframe if already disabled (Uma)
v2:
- Update HDMI AVI infoframe during fastset.
