[PATCH] drm/i915: Reduce duplicated switch cases in hpd code

[Ville Syrjala <ville.syrjala@xxxxxxxxxxxxxxx>]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

With GEN11_HOTPLUG_CTL_LONG_DETECT(), SHOTPLUG_CTL_DDI_HPD_LONG_DETECT()
and ICP_TC_HPD_LONG_DETECT() taking the hpd_pin as their argument
we can remove some duplication in the long_detect() switch statements.
