libata: normalize port_info, port_operations and sht tables
Over the time, port info, ops and sht structures developed quite a bit
of inconsistencies. This patch updates drivers.
* Enable/disable_pm callbacks added to all ahci ops tables.
* Every driver for SFF controllers now uses ata_sff_port_start()
instead of ata_port_start() unless the driver has custom
implementation.
* Every driver for SFF controllers now uses ata_pci_default_filter()
unless the driver has custom implementation.
* Removed an odd port_info->sht initialization from ata_piix.c.
Likely a merge byproduct.
* A port which has ATA_FLAG_SATA set doesn't need to set cable_detect
to ata_cable_sata(). Remove it from via and mv port ops.
* Some drivers had unnecessary .max_sectors initialization which is
ignored and was missing .slave_destroy callback. Fixed.
* Removed unnecessary sht initializations port_info's.
* Removed onsolete scsi device suspend/resume callbacks from
pata_bf54x.
* No reason to set ata_pci_default_filter() and bmdma functions for
PIO-only drivers. Remove those callbacks and replace
ata_bmdma_irq_clear with ata_noop_irq_clear.
* pata_platform sets port_start to ata_dummy_ret0. port_start can
just be set to NULL.
* sata_fsl supports NCQ but was missing qc_defer. Fixed.
* pata_rb600_cf implements dummy port_start. Removed.
