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(). Correct the PCM info, set the DMA address
and use the standard helper for handling the mmap on all architectures
properly.

PCM core deals the empty ioctl field now as default(*).
Let's kill the redundant lines.

The io-mapped buffers used in msnd drivers need __iomem annotations.
This fixes sparse warnings like:
sound/isa/msnd/msnd_pinnacle.c:172:45: warning: incorrect type in initializer (different address spaces)

Make these const as they are only used in a copy operation.

snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.

snd_msnd_pcm() takes a pointer to a pointer of a PCM where if this parameter
is provided the newly allocated PCM is stored. All callers pass NULL though,
so remove the parameter. This makes the code a bit cleaner and shorter.

Lots of sound drivers were getting module.h via the implicit presence
of it in <linux/device.h> but we are going to clean that up. So
fix up those users now.
