[PATCH] libata: interrupt driven pio for libata-core
- add PIO_ST_FIRST for the state before sending ATAPI CDB or sending
"ATA PIO data out" first data block.
- add ATA_TFLAG_POLLING and ATA_DFLAG_CDB_INTR flags
- remove the ATA_FLAG_NOINTR flag since the interrupt handler is now
aware of the states
- modify ata_pio_sector() and atapi_pio_bytes() to work in the interrupt
context
- modify the ata_host_intr() to handle PIO interrupts
- modify ata_qc_issue_prot() to initialize states
- atapi_packet_task() changed to handle "ATA PIO data out" first data block
- support the pre-ATA4 ATAPI device which raise interrupt when ready to
receive CDB
