Some high resolution codecs support 705.6KHz and 768KHz rates. So extend supported sample rate to 768kHz in pcm.h.

How many devices require it for now?
I have two devices, AK4458, AK5558.
I don't want to extend the core definitions blindly unless those rates are really commonly used. You can add those specific rates in the codec driver instead.
Ok, this is an option.
thanks,
