drm/i915/mtl: Add HDCP GSC interface
MTL uses GSC command streamer i.e gsc cs to send HDCP/PXP commands
to GSC f/w. It requires to keep hdcp display driver
agnostic to content protection f/w (ME/GSC fw) in the form of
i915_hdcp_fw_ops generic ops.
Adding HDCP GSC CS interface by leveraging the i915_hdcp_fw_ops generic
ops instead of I915_HDCP_COMPONENT as integral part of i915.
Adding checks to see if GSC is loaded and proxy is setup
