ALSA: core: Add memory copy helpers between iov_iter and iomem
Add two more helpers for copying memory between iov_iter and iomem,
which will be used by the new PCM copy ops in a few drivers.
The existing helpers became wrappers of those now.
Note that copy_from/to_iter() returns the copied bytes, hence the
error condition is adjusted accordingly.
