Based on HDCP1.4 framework introduced by Sean Paul, this series
implements the HDCP2.2 in I915.

The sequence for HDCP2.2 authentication and encryption is implemented
in I915. Encoder specific implementations are moved into hdcp_shim.

Intel HWs supports HDCP2.2 through ME FW. Hence this series
introduces a client driver for mei bus, so that for HDCP2.2
authentication, HDCP2.2 stack in I915 can avail the services from

Userspace interface remains unchanged as version agnostic. When
userspace request for HDCP enable, Kernel will detect the HDCP source
and sink's HDCP version(1.4/2.2)capability and enable the best capable
version for that combination.

This series enables the HDCP2.2 for Type0 content streams.

Yes its bit lengthy series. Please tolerate. Thanks

Major Changes in v2:
  - Synchronous implementation of HDCP authentication [SeanPaul]
  - Removal of bit-fields usage.[Tomas and Jani]
  - Protecting the mei_interface handle with mutex [Chris]
  - Droped, added and squashed few patches
  - Extended hdcp_shim to support hdcp2.2 operations too. [SeanPaul]
  - Used Intel_wait_for_registers(), Where ever it is applicable.[Chris]
  - mei_hdcp driver is moved into drivers/misc/mei/hdcp/ [Tomas]
  - Adapted the static declaration for struct intel_hdcp and mei_hdcp_data.

Sincere thanks for Sean Paul, Jani Nikula, Chris Wilson and Tomas Winkler
for the review comments on v1 series.
