ide-4drives: manage I/O resources in driver

* Tell IDE layer to not manage resources by setting hwif->mmio flag.

* Use {request,release}_region() for resources management.

* Use driver name for resources management.

* Remove no longer needed 'hwif->chipset == ide_4drives' handling
  from ide_device_add_all().
