drm/i915: extract intel_hdcp.h from intel_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm: Move port definition back to i915 header We dont need the definition of the enum port outside I915, anymore. Hence move enum port definition into I915 driver itself. v2: intel_display.h is included in intel_hdcp.h v3: enum port is declared in headers. v4: commit msg is rephrased. v5: copyright year is updated [Tomas] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> Reviewed-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190828164216.405-3-ramalingam.c@intel.com

drm/i915/hdcp: Nuke intel_hdcp_transcoder_config() intel_hdcp_transcoder_config() is clobbering some globally visible state in .compute_config(). That is a big no no as .compute_config() is supposed to have no visible side effects when either the commit fails or it's just a TEST_ONLY commit. Inline this stuff into intel_hdcp_enable() so that the state only gets modified when we actually commit the state to the hardware.
