[PATCH] libata CHS: calculate read/write commands and protocol on the fly (revise #6)

Browse Source 
- 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
