Add 96KHz rate support for SoundWire jack device.

Looks ok although it's not quite common to not have any users yet in the tree. adding @singalsu to check the usage. This will have to use SRC or otherwise will be of limited use towards user-space.

As far as I know, we always expose single sample rate to user space. Not sure if SRC is necessary, I set the same rate to all elements in the entire path.

1st step is to enable the interface at the new rates so that aplay can directly use the new rates. 2nd step is SRC etc.
