[Intel-gfx] [PATCH 08/20] drm/i915: Parametrize BXT_DE_PORT_HP_DDI with hpd_pin

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Use hpd_pin to parametrize BXT_DE_PORT_HP_DDI() to make it clear
these have nothing to do with DDI ports or PHYs as such. The only
thing that matters is the HPD pin assignment.
