We can't specify which mode in the cases below but we can at least say
PIO and look consistent with the default.

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.

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.

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.

When set_mode() changed ->set_mode didn't adapt. This makes the needed

sht->max_sectors is overrided unconditionally in ->slave_configure.
There's no reason to set it to any value.

The RZ1000 is a generic device except that it has a readahead fifo flaw
that corrupts. We force this off at init time but we want to be paranoid
and force it off at resume as well. I don't know of any actual hardware
that supports both RZ1000 and suspend to RAM but given its a disk muncher
better safe than sorry.

Many LLDs are missing sht->slave_destroy.  The method is mandatory to
support device warm unplugging (echo 1 > /sys/.../delete).  Without
it, libata might access released scsi device.

The PATA driver set got converted to the new error handling setup, but
the old hooks were accidentally left in place.  Now, removed.
