[PATCH v2 1/5] drm/connector: Create a helper to attach the hdr_output_metadata property
All the drivers that implement HDR output call pretty much the same function to initialise the hdr_output_metadata property, and while the creation of that property is in a helper, every driver uses the same code to attach it.
Provide a helper for it as well

All the drivers that support the HDR metadata property have a similar function to compare the metadata from one connector state to the next, and force a mode change if they differ.
All these functions run pretty much the same code, so let's turn it into an helper that can be shared across those drivers.

The intel driver uses the same logic to attach the Colorspace property in multiple places and we'll need it in vc4 too. Let's move that common code in a helper.

Our driver while supporting HDR didn't send the proper colorimetry info in the AVI infoframe.
Let's add the property needed so that the userspace can let us know what the colorspace is supposed to be.
