drivers/misc: add HDCP 2.2 driver
Implement the HDCP 2.2 feature for external interfaces such as
the DisplayPort interface. The HDCP 2.2 driver manages the
authentication process by initiating message exchange between
the external interface (Receiver) and the QTI Secure Execution
Environment (QSEE).
This implementation is based on a snapshot of the HDCP 2.2 driver
as of this commit If693a9d4c8561 ("drivers/misc: make the HDCP lib
a standalone driver") on kernel-4.4.
