[Intel-gfx] [PATCH 02/18] drm/i915: Add DP VSC SDP payload data to intel_crtc_state.infoframes

[Gwan-gyeong Mun]

In order to support state readout for DP VSC SDP, we need to have a
structure which holds DP VSC SDP payload data such as
"union hdmi_infoframe drm" which is used for DRM infoframe.

And In order to support DP HDR10, we have to support VSC SDP and
HDR Metadata Infoframe SDP. As we will use drm member variable of
intel_crtc_state.infoframes, we only need to add vsc sdp member variable
to intel_crtc_state.infoframes.

Because DP SDP payload type does not have common structure like as
"union hdmi_infoframe", it adds "struct intel_dp_vsc_sdp"
to intel_display_types.h
