ATA_FLAG_IRQ_MASK was added when I did the original data transfer with
IRQ masked bits for PIO. It has since been replaced by ->pio_data_xfer
methods so should be removed so nobody uses it by mistake thinking it
still works.

We need to pass the device in order to do per device checks such as
32bit I/O enables. With the changes to include dev->ap we now don't have
to add parameters however just clean them up. Also add data_xfer methods
to the existing drivers except ata_piix (which is in the other block of
patches). If you reject the piix one just add a data_xfer to it...

Fix the HSM error_mask mapping.
Changes:
- Better mapping in ac_err_mask()
- In HSM_ST_FIRST ans HSM_ST state, check ATA_ERR|ATA_DF and map it to AC_ERR_DEV instead of AC_ERR_HSM.
- In HSM_ST_FIRST and HSM_ST state, map DRQ=1 ERR=1 to AC_ERR_HSM.
- For PIO data in and DRQ=1 ERR=1, add check after the junk data block is read.

Add ap->qc_active and ap->sactive, mask of all active qcs and libata's
view of the SActive register, respectively. Also, implement
ata_qc_complete_multiple() which takes new qc_active mask and complete
multiple qcs according to the mask.
These will be used to track NCQ commands and complete them. The
distinction between ap->qc_active and ap->sactive is also useful for
later PM implementation.
