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]
