The old ISA MSND driver basically maps the iomem as the DMA buffer.
For this type of buffer, we have already the standard mmap helper,
snd_pcm_lib_mmap_iomem().  Set the DMA address and use the standard
helper for allowing the mmap on all architectures properly.
We need to set the different PCM INFO flag for this.
Will resubmit v2 patch covering that, too.
