This patch converts the drivers in drivers/ata/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

Currently, the device tree of ata port and scsi host looks as below, /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) This patch makes ata port as parent device of scsi host, then it becomes /sys/devices/pci0000:00/0000:00:1f.2 (ahci controller) |-- ata1 (ata port) |-- host0 (scsi host) |-- target0:0:0 (scsi target) |-- 0:0:0:0 (disk) With this change, the ata port runtime PM is easier. For example, the ata port runtime suspend will happen as, disk suspend --> scsi target suspend --> scsi host suspend --> ata port suspend.

This is another attempt at fixing the same problem that 270dac35 (libata: ahci_start_engine compliant to AHCI spec) tried to solve. Unfortunately, 270dac35 created regressions for a lot more common controllers and got reverted. This specific AHCI IP block becomes a brick if the DMA engine is started while DRQ is set. It is not possible to avoid the condition completely but the most common occurrence is caused by spurious use of ahci_start_engine() from ahci_start_port() during init sequence. DMA engine is started after both soft and hard resets and ahci_start_port() is always followed by resets, so there is no reason to start DMA engine from ahci_start_port(). This patch removes ahci_start_engine() invocation from ahci_start_port(). This change makes failure path of ahci_port_suspend() leave engine stopped without following resets. This is resolved by replacing ahci_start_port() call with ata_port_freeze() which forces resets afterwards, which is the better behavior anyway.

Reenable sending SRST to devices connected behind a Sil3726 PMP. This allow staggered spinups and handles drives that spins up slowly. While the drives spin up, the PMP will not accept SRST. Most controller reissues the reset until the drive is ready, while some [Sil3124] returns an error. In ata_eh_error, wait 10s before reset the ATA port and try again.

Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq() so the latter can be also used for host controllers supporting 32-bit PIO operations. It is a completely safe thing to do because if 32-bit PIO is not supported or enabled ata_sff_data_xfer32() will fallback to a standard method.
