Add the audio clock controller which is part of the audio bus
This controller takes 8 input plls, and the usual clock gate, from the
main clock controller. It provides for the all the devices of the audio
subsystem, such as tdms, spdif, pdm, etc.

Kevin,
Please note that this change depends on the axg audio clock bindings [0].
It will be part of our PR to clock in this cycle.
As usual, I've prepared a topic branch with the DT changes for you.
Please, let me know when you need a tag on it.
Cheers
Jerome
