[Intel-gfx] [PATCH 1/7] drm/i915: Replace aux_ch_ctl_reg check with port check

[ville.syrjala at linux.intel.com]

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

Instead of checking what aux_ch_ctl_reg is, we can simply check the port
when determining the right timeout value to program.

v2: Reorder patches to reduce churn (Chris)
