* Keep pointer to ->init_chipset method also in
struct ide_host and set it in ide_host_alloc_all().
* Add ide_pci_suspend() and ide_pci_resume() helpers
(default ->suspend and ->resume implementations).
* ->init_chipset can no longer be marked __devinit.
* Add proper PCI PM support to IDE PCI host drivers
(rz1000.c and tc86c001.c are skipped for now since
they need to be converted from using ->init_hwif
to use ->init_chipset instead).
v2:

* Add struct ide_devset, S_* flags, *DEVSET() & ide*_devset_*() macros.

* Use 'const struct ide_devset **settings' in ide_drive_t instead of

drivers to use struct ide_devset and co.:
- device settings are no longer allocated dynamically for each device
but instead there is an unique struct ide_devset instance per setting
- device driver keeps the pointer to the table of pointers to its
settings in ide_driver_t.settings
- generic settings are kept in ide_generic_setting[]

ide_{read,write}_setting() and proc_ide_{read,write}_settings()

After rework settings will be no longer created dynamically
for each device so we need to make some fixups first.
* Use set_[ksettings,unmaskirq]() as a set function for
["keepsettings","unmaskirq"] setting.
* Allow writes to ["io_32bit","unmaskirq"] settings also when
drive->no_[io_32bit,unmask] is set (this is checked later inside
set_[io_32bit,unmaskirq]() anywyay and keeps consistency with
the corresponding HDIO_SET_[32BIT,UNMASKINTR] ioctls).
* Use max possible multi sectors value (16) as an allowed max for
"multcount" setting. set_multcount() set function checks against
device's max possbile value anyway and it makes the proc setting
consistent with the corresponding HDIO_SET_MULTCOUNT ioctl.
