ALSA: pcm: add support for 705.6kHz and 768kHz sample rates

Many modern codecs support 705.6kHz and 768kHz sample rates. Current HW
params fail to set 705.6kHz and 768kHz sample rates as these are not in the
known-rates list.

Add these new rates to the known-rates list to allow them.

Also add defines in pcm.h so that drivers can use it.
