ALSA: pcm.h: Add rate defines for 352k8 and 384k

Add SNDRV_PCM_RATE_352800 and SNDRV_PCM_RATE_384000 defines to pcm.h,
 for 352k8 and 384k sample rates.

Add SNDRV_PCM_RATE_8000_384000 define.

Update rates list.

Yes, we can use CONTINUOUS/KNOT and constraints, to support the x8
sample rates, but having the defines requires less code in drivers.

Many more DAC chips are now supporting the x8 44k1/48k multiples.

From a high-res viewpoint, the DXD standard is 352k8, 24 bit.
That alone should justify the addition of a define for it. ;)
