ide: manage I/O resources in ide_legacy_init_one() 

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

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

* Set ->name field of 'struct ide_port_info' instances in legacy VLB
  host drivers and use driver name for resources management.
