drm/i915: MEI interface implementation
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]
v8:
subcomponent name is dropped as it is already merged.
