* Hardreset must not exit without actually performing reset regardless
of link status. We're resetting the link after all.
* Minor message update.
* 150ms delay is meaningful iff link is online after reset is
complete.

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.

Driver for Initio 162x SATA controllers. ATA r/w, ATAPI r, hotplug
and suspend/resume work. ATAPI w (recording, that is) broken. Feel
free to fix it, but be warned, this controller is weird.
