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 v14 - enum port is moved into the drm/i915_drm.h - Small fixes for mei_hdcp Kernel-Doc - ICL device ID patch is already merged. So dropped it. - Couple of patches are merged already. So dropped them.
