soft: kmod_scripts: initial import

set of basic bash scripts to remove/insert SOF Linux kernel modules in
the right order.  This is typically used to avoid rebooting every time
the SOF image or topology are updated - and detect leaks on remove.

sof_remove.sh: remove all SOF modules
sof_insert.sh: probe SOF modules
sof_bootone.sh: combination of remove/insert in one shot
sof_bootloop.sh: boot loop to see if firmware boot is reliable over
time

This can probably be enhanced to remove spurious "module is not
currently loaded" logs.
