snd_cs46xx_proc_init() stores the chip in the private data of the five
region entries, but snd_cs46xx_io_read() reads that back as the region,
so a read of /proc/asound/cardN/CS46xx_BA0 and friends copies from
whatever sits at the region's offset in struct snd_cs46xx instead of
the mapped registers. Store the region.
