drm/i915/hdcp: Use generic names for HDCP helpers and structs

pre MTL we interact with mei interface to talk to
firmware and enable CP but going forward we will talk to gsc cs
because of which we are making all names for HDCP helpers and
structures generic as either mei or gsc cs maybe used.

Change the include/drm/i915_mei_hdcp_interface.h to
include/drm/i915_hdcp_interface.h

Change the i915_hdcp_interface.h header naming convention to
suit generic f/w type.
%s/MEI_/HDCP_
%s/mei_dev/hdcp_dev

Change structure name Accordingly.
%s/i915_hdcp_comp_master/i915_hdcp_master
%s/i915_hdcp_component_ops/i915_hdcp_ops

--v6
-make each patch build individually [Jani]

--v8
-change ME FW to ME/GSC FW [Ankit]
-fix formatting issue [Ankit]

--v9
-fix commit message and header [Uma]

--v10
-rename comp variable [Uma]
