From: Anshuman Gupta <anshuman.gupta@xxxxxxxxx>
As now we have more then one type of content protection
secrity firmware. Let change the i915_cp_fw_hdcp_interface.h
header naming convention to suit generic f/w type.
%s/MEI_/FW_
%s/mei_fw/cp_fw
%s/mei_dev/fw_dev
As interface to CP FW can be either a non i915 component or
i915 intergral component, change structure name Accordingly.
