[Intel-gfx] [PATCH 5/5] drm/i915: Don't check tc_mode unless dealing with a TC PHY

From: Ville Syrjälä We shouldn't really trust tc_mode on non-TC PHYs since we never initialize it explicitly. So let's check for the PHY type first. Fortunately TC_PORT_TBT_ALT happens to be zero so I don't think there's an actual bug here, just a possibility for a future one if someone rearrange
