[PATCH v2 2/4] drm/i915/dp: Move initialization of hpd_pin to a new function

[Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com>]

This shaves a few lines from intel_dp_init_connector() and will serve as
a good place to add other port specific information in a follow up
patch.

While at it, convert BUG() to MISSING_CASE() in the default case.

v2: s/BUG/MISSING_CASE. (Chris)
