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 v12
- hdcp disable from unbind is removed.
- hdcp component init and del are moved away from conenctor ops.
- Review comemnts from Tomas are addressed. [Tomas]
- Collected the r-bs and Acks given for v11.
- ICL mei dev id patch is cherry-picked from
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git char-misc-linus
- Changes for component framework are merged into drm-tip already.

Now that component has docs it's worth spending a few words and
hyperlinks on recommended best practices in drm.
