drm/i915/icl: Implement half float formats
64 bpp half float formats are supported on hdr planes only and are subject to the following restrictions: * 90/270 rotation not supported * Yf Tiling not supported * Frame Buffer Compression not supported * Color Keying not supported v2: - Drop handling pixel normalize register - Don't use icl_is_hdr_plane too early v3: - Use refactored icl_is_hdr_plane (Ville) - Use u32 instead of uint32_t (Ville) v6: - Rebase and fix merge conflicts - Reorganize switch statements to keep RGB grouped separately from YUV Cc: Uma Shankar <uma.shankar@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Kevin Strasser <kevin.strasser@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Adam Jackson <ajax@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1552437513-22648-4-git-send-email-kevin.strasser@intel.com
