ALSA: hda - FIX to not expose SPDIF on Thinkpad X301, since it does not have the ability to use SPDIF

The Lenovo X301 does not have the ability to connect to a docking
station to use the SPDIF port. It also does not have the ability to do
SPDIF though the headphone jack or Display Port jacks.

This patch fixes it so this is not exposed for the X301 and users do
think it has the ability to do SPDIF.

I tested both headphone & display port jacks and it is not there. I have
tested this patch and it works great.

Also to add the other Thinkpads have different subsystem codec IDs.
Here are examples:
