Add support for multiple mst stream in hdcp port data which will be used by RepeaterAuthStreamManage msg and HDCP 2.2 security f/w for m' validation. Security f/w doesn't have any provision to mark the stream_type for each stream separately, it just take single input of stream_type while authenticating the port and applies the same stream_type to all streams. So driver mark each stream_type with common highest supported content type for all streams in DP MST Topology. Security f/w supports RepeaterAuthStreamManage msg and m' validation only once during port authentication and encryption. Though it is not compulsory, security fw should support dynamic update of content_type and should support RepeaterAuthStreamManage msg and m' validation whenever required. v2: - Init the hdcp port data k for HDMI/DP SST stream. v3: - Cosmetic changes. [Uma] v4: - 's/port_auth/hdcp_port_auth'. [Ram] - Commit log improvement. v5: - Comment and commit log improvement. [Ram] v6: - Check first connector connected status before intel_encoder_is_mst to avoid any NULL pointer dereference.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
