drm/i915: extract intel_ddi.h from intel_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm/i915: Pass atomic state to encoder hooks We're going to want access to the atomic state for iterating the slave crtcs when enabling the port sync master crtc. Pass the atomic state all the way down. The alternative would be yet another encoder hook which we'll have to call after all the normal modeset stuff is done. Not really a fan of yet another hook just for this. Note that during readout state sanitation we are now going to pass NULL as the atomic state since we don't have one. We need to change that and then we can also s/crtc_state/crtc/ and s/conn_state/conn/ for the encoder hooks as well.

drm/i915/dp: Add support of BT.2020 Colorimetry to DP MSA When BT.2020 Colorimetry output is used for DP, we should program BT.2020 Colorimetry to MSA and VSC SDP. In order to handle colorspace of drm_connector_state, it moves a calling of intel_ddi_set_pipe_settings() function into intel_ddi_pre_enable_dp(). And it also rename intel_ddi_set_pipe_settings() to intel_ddi_set_dp_msa(). As per DP 1.4a spec section 2.2.4 [MSA Data Transport] The MSA data that the DP Source device transports for reproducing the main video stream. Attribute data is sent once per frame during the main video stream’s vertical blanking period. In order to distinguish needed colorimetry for VSC SDP, it adds intel_dp_needs_vsc_sdp function. If the output colorspace requires vsc sdp or output format is YCbCr 4:2:0, it uses MSA with VSC SDP. As per DP 1.4a spec section 2.2.4.3 [MSA Field for Indication of Color Encoding Format and Content Color Gamut] while sending BT.2020 Colorimetry signals we should program MSA MISC1 fields which indicate VSC SDP for the Pixel Encoding/Colorimetry Format. v2: Remove useless parentheses v3: Addressed review comments from Ville - In order to checking output format and output colorspace on intel_dp_needs_vsc_sdp(), it passes entire intel_crtc_state struct value. - Remove a pointless variable. v9: Addressed review comments from Ville - Remove a duplicated output color space from intel_crtc_state. - In order to handle colorspace of drm_connector_state, it moves a calling of intel_ddi_set_pipe_settings() function into intel_ddi_pre_enable_dp().
