The change to the devres layer re-orders the execution of cleanup
functions and in turn causes the pcmcia layer to oops as it zaps a
pointer now needed later on. We simply leave the pointer alone.

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.

As we read out the manufactor and card_id from the PCMCIA device in the
PCMCIA core, and device drivers can access those reliably in struct
pcmcia_device's fields manf_id and card_id, remove additional (and partly
broken) manf_id and card_id detection logic from PCMCIA device drivers.

This fixes support for rev c8 of the ALi/ULi PATA, and keeps pcmcia in
sync so ide_cs and pata_pcmcia are interchangable, both are only changes
to constants.

Right now rev 0xC8 and higher don't work with libata but 0xc8 is in the
field now.
