246ce3b675 libata: add another IRQ calls (libata drivers)
This patch is against each libata driver.

Two IRQ calls are added in ata_port_operations.
- irq_on() is used to enable interrupts.
- irq_ack() is used to acknowledge a device interrupt.

In most drivers, ata_irq_on() and ata_irq_ack() are used for
irq_on and irq_ack respectively.

In some drivers (ex: ahci, sata_sil24) which cannot use them
as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

0d5ff56677 libata: convert to iomap
Convert libata core layer and LLDs to use iomap.

* managed iomap is used.  Pointer to pcim_iomap_table() is cached at
  host->iomap and used through out LLDs.  This basically replaces
  host->mmio_base.

* if possible, pcim_iomap_regions() is used

Most iomap operation conversions are taken from Jeff Garzik
<jgarzik@pobox.com>'s iomap branch.

24dc5f33ea libata: update libata LLDs to use devres
Update libata LLDs to use devres.  Core layer is already converted to
support managed LLDs.  This patch simplifies initialization and fixes
many resource related bugs in init failure and detach path.  For
example, all converted drivers now handle ata_device_add() failure
gracefully without excessive resource rollback code.

As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down.  Note that freezing is enough in many cases
and ports are automatically frozen before being detached.

2eab80ac0c [PATCH] libata: kill unnecessary sht->max_sectors initializations
sht->max_sectors is overrided unconditionally in ->slave_configure.
There's no reason to set it to any value.

7e45b0e5f6 [PATCH] libata: Winbond support
Winbond 83759A support in non-multichip mode (afaik nobody ever used
multichip mode anyway). The 83759 is not supported by this driver as it
is already handled elsewhere and doens't use the same interfaces.
