Starting from v1.7 the installation process has been simplified and
the go.sh script is not used anymore. Instead:

```
sudo mv /lib/firmware/intel/sof* some_backup_location/
sudo mv /usr/local/bin/sof-*     some_backup_location/ # optional
sudo ./install.sh v1.N.x/v1.N-rcM
```

The go.sh script still applies to older releases.

You don't have to use install.sh, you can use any recursive copy of
your preference. This is all what install.sh does, example with v1.7.x/v1.7:

```
cd v1.7.x
rsync -a sof*v1.7   /lib/firmware/intel/
ln -s sof-v1.7      /lib/firmware/intel/sof
ln -s sof-tplg-v1.7 /lib/firmware/intel/sof-tplg
rsync tools-v1.7/*  /usr/local/bin
```

If you don't want the symbolic links:

```
rsync -a sof-v1.7/       /lib/firmware/intel/sof/
rsync -a sof-tplg-v1.7/  /lib/firmware/intel/sof-tplg/
rsync tools-v1.7/        /usr/local/bin/
```

Remember that for rsync (and some versions of `cp`), a trailing slash in
srcdir/ is roughly equivalent to srcdir/* + srcdir/.??*
