	Defining the mei-i915 interface functions and initialization of the interface. v2: Adjust to the new interface changes. [Tomas] Added further debug logs for the failures at MEI i/f. port in hdcp_port data is equipped to handle -ve values. v3: mei comp is matched for global i915 comp master. [Daniel] In hdcp_shim hdcp_protocol() is replaced with const variable. [Daniel] mei wrappers are adjusted as per the i/f change [Daniel] v4: port initialization is done only at hdcp2_init only [Danvet] v5: I915 registers a subcomponent to be matched with mei_hdcp [Daniel] v6: HDCP_disable for all connectors incase of comp_unbind. Tear down HDCP comp interface at i915_unload [Daniel] v7: Component init and fini are moved out of connector ops [Daniel] hdcp_disable is not called from unbind. [Daniel] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> [v11] [danvet: For the topic/mei-hdcp shared branch drop everything but the header change needed by both drm/i915 and mei-hdcp. Also drop the no longer needed device.h include.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/1550219730-17734-6-git-send-email-ramalingam.c@intel.com
