ALSA/ASoC: hda: ext: add 'bus' prefix for multi-link stream setting

All the helpers dealing with multi-link configurations are located in
the hdac_ext_controller.c, except the two set/clear routines that
modify the LOSIDV registers.

For consistency, move the two helpers and add the 'bus' prefix. One
could argue that the 'ml' prefix might be more relevant but that would
be a larger code change.

No functionality change, just move and rename.
