[PATCH v10 00/40] drm/i915: Implement HDCP2.2

This series enables the HDCP2.2 Type 0 for I915. The sequence for
HDCP2.2 authentication and encryption is implemented as a generic flow
between HDMI and DP. 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
ME FW. To enable this client driver set the config variable
CONFIG_INTEL_MEI_HDCP.

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.

Major changes in v10:
- I915-MEI interface is implemented with component framework.
- I915 detects the mei_hdcp device availability to enabled HDCP2.2.

Hopefully we are near the end of this series.
