[PATCH] libata CHS: calculate read/write commands and protocol on the fly (revise #6)
- merge ata_prot_to_cmd() and ata_dev_set_protocol() as
ata_rwcmd_protocol()
- pave road for read/write multiple support
- remove usage of pre-cached command and protocol values and call
ata_rwcmd_protocol() instead
