New loop now takes into account pages not physically contiguous.
Also some minor improvements, e.g. make the spin_lock used more locally,
reuse a group we had if we had one, etc.

This implements a skeleton setup function and call it on ioctl
Many missing points:
- missing pci mapping to make setup work
- no clear (passed to linux, so will likely bug out)
- missing locks/safe-guards

Fix other warnings
...
Most were harmless, but the change to ACCESS_ONCE from volatile
cast is probably useful.
Expanding macro, we basically went from:
m = (volatile struct sdma_vl_map *)dd->sdma_map;
to
m = *(volatile struct sdma_vl_map **)&(dd->sdma_map);
i.e. the explicit lookup is at a different level.
