ramdisk: enable interactive features for array-parameters

Our interactive governor is capable of arrays in some
parameters, however if they aren't set at boot some apps
can't change them in realtime (like AeroControl).

This change enables this feature. Furthermore it may help
with the in-call delay a little bit.
