ALSA: patch_sigmatel: Add missing Gateway entries and autodetection

Gateway autodetection and entries are incomplete.

This patch adds the entries found at the .INI file for their driver version
5.10.5082.0.

It also uses the proper code to seek for notebook ID, since this is based on
codec subsystem ID on those devices.

This should provide a proper pinup for several gateways notebooks:

Since some entries conflict with existing pinups, I'm providing a separate
patch to fix those entries.

Tested only with Gateway MX6453.
