Sepolicy: Add sysfs L3 permissions to init_shell domain on SDM710

Browse source 
Cdsprpcd domain listens to L3 clock requests from CDSP and votes
for CPU L3 frequency via sysfs_devfreq_l3cdsp node. The change
allows init shell to modify l3-cdsp governor to userspace
facilitating Cdsprpcd daemon in voting for L3 clock on SDM710.
