[Intel-gfx] [PATCH v2 1/7] drm/i915: move ibx_digital_port_connected to intel_dp.c

[Jindal, Sonika]

Hmm, so we might need to make it global again, because we would want to check the live status for hdmi in the hdmi optimization series:
http://lists.freedesktop.org/archives/intel-gfx/2015-August/074306.html 
Maybe we can drop this patch alone?

Regards,
Sonika

The function can be made static there. No functional changes.
