Imre Deak bd48006178 drm/i915/bxt: Don't reprogram an already enabled DDI PHY
If BIOS has already programmed and enabled a PHY, don't reprogram it as
that may interfere with the currently active outputs. A follow-up patch
will add state verification, so we can catch any misconfiguration on
BIOS's behalf.
