ASoC: sdw_utils: generate combined spk components string

Browse Source 
The suggestion from UCM for 2 speaker components is using 1 "spk" tag
with 2 component names. Like "spk:rt722+rt1320". The commit removes the
creation of the "spk" components in each rtd_init callback and creat the
string in asoc_sdw_rtd_init().
