kms_content_protection: Content type support
Adds a connector property called "CP_Content_Type"
Content Type takes two values which classifies the content stream:
Type 0: Stream that can be transmitted on HDCP1.4/HDCP2.2
Type 1: Stream that needs HDCP2.2 encryption only.
So when Type 1 is set KMD is forced to enable HDCP2.2 only.
For Type 0 request, Kernel chooses the highest capable HDCP version
(v2.2) first. If that fails, then it fall back to the next available
version(v1.4) before abondoning HDCP authentication attempts.
Please note content_type is allowed to be updated when "Content
Protection" is in UNDESIRED state.
v2:
s/cp_content_type/content_protection_type [danvet]
v3:
s/content_protection_type/HDCP Content Type [Pekka]
v4:
Rebased
v5:
Typos in the commit msg is fixed [Uma]
