DRM connector property is created to represent the content protection state of the connector and to configure the same.
Content protection states defined: DRM_MODE_CONTENT_PROTECTION_UNSUPPORTED - Unsupported DRM_MODE_CONTENT_PROTECTION_DISABLE - Disabled DRM_MODE_CONTENT_PROTECTION_ENABLE - Enabled
v2: Redesigned the property to match with CP needs of CrOS [Sean].
v3: Renamed the state names. Header is removed [sean].

You're still changing the enum names from the original patch/CrOS implementation.
