Tejun Heo e1be5d73e0 sata_via: fix resource-managed iomap conversion
Conversion to resource-managed iomap was buggy causing init failures
on both vt6420 and 6421 - BAR5 wasn't mapped for both controllers
while on vt6420 sata_via tried to map BAR0-4 twice.  Fix it.

Akira Iguchi 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.

Tejun Heo 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.

Tejun Heo 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.

Tejun Heo d025987217 sata_via: style clean up, no indirect method call in LLD
Call ata_bmdma_irq_clear() directly instead of through
ap->ops->irq_clear() according to libata style guideline.

Tejun Heo 17234246eb sata_via: don't diddle with ATA_NIEN in ->freeze
vt6420 completely loses its ability to raise IRQ for ATAPI devices if
ATA_NIEN is diddled with in ->freeze.  Further investigation is
necessary to determine whether this problem is shared on other
controllers but it doesn't seem to be at this point.

Make vt6420's ->freeze only clear IRQ to fix this problem.  This makes
vt6420 relatively more prone to IRQ storms but the controller is way
too braindamaged to worry about that anyway.

Jeff Garzik cca3974e48 libata: Grand renaming.
The biggest change is that ata_host_set is renamed to ata_host.

* ata_host_set			=> ata_host
* ata_probe_ent->host_flags	=> ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags	=> ata_probe_ent->_host_flags
* ata_host_stats		=> ata_port_stats
* ata_port->host		=> ata_port->scsi_host
* ata_port->host_set		=> ata_port->host
* ata_port_info->host_flags	=> ata_port_info->flags
* ata_(.*)host_set(.*)\(\)	=> ata_\1host\2()

The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose.  Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.

ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.
