alsa: strip and add the _alibpref from device names

Browse source 
Strip the _alibpref from the device name, it contains a local counter
to identify the ucm card that should remain internal. We set a flag on
the device to notify of this.

Re-add the _alibpref of the local card to the device name if the
device was flagged.

See #1286
