Cássio Gabriel 83fbbcb793 ALSA: virtio: Add missing 384 kHz PCM rate mapping 
The VirtIO sound UAPI defines VIRTIO_SND_PCM_RATE_384000, and ALSA
has SNDRV_PCM_RATE_384000. However, virtio-snd's rate conversion
tables stop at 192 kHz.

A device advertising only 384 kHz is rejected as having no supported
PCM frame rates. A device advertising 384 kHz together with lower rates
does not expose 384 kHz through the ALSA hardware constraints. The
selected ALSA rate also needs a reverse mapping for SET_PARAMS.

Add the missing 384 kHz entries to both conversion tables.

Fixes: 29b96bf50b ("ALSA: virtio: build PCM devices and substream hardware descriptors")
Fixes: da76e9f3e4 ("ALSA: virtio: PCM substream operators")
