ALSA: usb-audio: Add static mapping table for ALC1220-VB-based mobos

Browse Source 
TRX40 mobos from MSI and others with ALC1220-VB USB-audio device need
yet more quirks for the proper control names.

This patch provides the mapping table for those boards, correcting the
FU names for volume and mute controls as well as the terminal names
for jack controls.  It also improves build_connector_control() not to
add the directional suffix blindly if the string is given from the
mapping table.

With this patch applied, the new UCM profiles will be effective.
