ata: declare ata_port_info structures as const

ata_port_info structures are either copied to other objects or their
references are stored in objects of type const. So, ata_port_info
structures having similar usage pattern can be made const.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM
where applicable. Benefits of this change:

* unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n
and CONFIG_PM_RUNTIME=y configurations

* easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in
the future

* more consistent code (there are host drivers which are using the correct
CONFIG_PM_SLEEP checks already)

The patch leaves the core libata code and ->port_[suspend,resume] support
in sata_[inic162x,nv,sil24].c alone for now.

ata: delete non-required instances of include <linux/init.h>

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Drivers: ata: remove __dev* attributes.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
