drm: Add HDR source metadata property
This patch adds a blob property to get HDR metadata information from userspace. This will be send as part of AVI Infoframe to panel. It also implements get() and set() functions for HDR output metadata property.The blob data is received from userspace and saved in connector state, the same is returned as blob in get property call to userspace. v2: Rebase and modified the metadata structure elements as per Ville's POC changes. v3: No Change v4: Addressed Shashank's review comments v5: Rebase. v6: Addressed Brian Starkey's review comments, defined new structure with header for dynamic metadata scalability. Merge get/set property functions for metadata in this patch. v7: Addressed Jonas Karlman review comments and defined separate structure for infoframe to better align with CTA 861.G spec. Added Shashank's RB. v8: Addressed Ville's review comments. Moved sink metadata structure out of uapi headers as suggested by Jonas Karlman. v9: Rebase and addressed Jonas Karlman review comments. v10: Addressed Ville's review comments, dropped the metdata_changed state variable as its not needed anymore.
