Now that all NCQ related stuff are in place, implement NCQ device
configuration and bump ATA_MAX_QUEUE to 32 thus activating NCQ
support.
Original implementation is from Jens Axboe.

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.

Rename ap->qactive to ap->qc_allocated. This is to accomodate
addition of ap->qc_active, mask of active qcs.
