Suraj Kandpal 4f60f06a41 drm/i915/hdcp: Convert intel_hdcp_enable to a blanket function
Let's convert intel_hdcp_enable to a blanket function
which just has some conditions which needs to be checked
before connectors enable hdcp.
This cleans up code and avoids code duplication.

--v3
-Keep function name as intel_hdcp_enable() [Jani]
