Add support for HDR metadata using the hdr_output_metadata connector property,
configure Dynamic Range and Mastering InfoFrame accordingly.

A use_drm_infoframe flag is added to dw_hdmi_plat_data that platform drivers
can use to signal when Dynamic Range and Mastering infoframes is supported.
This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version,
and only GXL support DRM InfoFrame.

The first patch add functionality to configure DRM InfoFrame based on the
hdr_output_metadata connector property.

The remaining patches sets the use_drm_infoframe flag on some SoCs supporting
Dynamic Range and Mastering InfoFrame.

v2 has been runtime tested on a Rock64 (RK3328) and Rock Pi 4 (RK3399),
only build tested for Amlogic and Allwinner.

Changes in v2:
  * address comments from Andrzej Hajda
  - renamed blob_equal to hdr_metadata_equal
  - renamed drm_infoframe flag to use_drm_infoframe
  - use hdmi_drm_infoframe_pack and a loop to write regs
  - remove hdmi version check in hdmi_config_drm_infoframe

Jonas Karlman (4):
  drm/bridge: dw-hdmi: Add Dynamic Range and Mastering InfoFrame support
  drm/rockchip: Enable DRM InfoFrame support on RK3328 and RK3399
  drm/meson: Enable DRM InfoFrame support on GXL, GXM and G12A
  drm/sun4i: Enable DRM InfoFrame support on H6
