utils: tuning: Add alsc-only libtuning raspberrypi tuning script

Browse source 
Add a tuning script for raspberrypi for alsc only, that uses libtuning.
Since there will also be a tuning script for raspberrypi that has more
modules, put the libtuning alsc module definition in a separate file so
that it can be reused later.
