ide: use generic power management
Earlier, drivers had to manage the device's power states, and related
operations, themselves. With the generic approach, these are done by PCI
core.
The ide_pci_suspend() and ide_pci_resume(), declared in
include/linux/ide.h and defined in drivers/ide/setup-pci.c, were external
and were exported. Those were then used by other source files.
Now, as they have to bind with dev_pm_ops object, there is no need to
export them and they can be made static.
Declare an extern const dev_pm_ops object in include/linux/ide.h and define
it in drivers/ide/setup-pci.c with SIMPLE_DEV_PM_OPS macro, binding
suspend, and resume callbacks with it. This object can now be used by other
source files.
The following source files are binding same dev_pm_ops object in their PM:
drivers/ide/aec62xx.c
drivers/ide/alim15x3.c
drivers/ide/amd74xx.c
drivers/ide/atiixp.c
drivers/ide/cmd64x.c
drivers/ide/cs5520.c
drivers/ide/cs5530.c
drivers/ide/cs5535.c
drivers/ide/cs5536.c
drivers/ide/cy82c693.c
drivers/ide/hpt366.c
drivers/ide/ide-pci-generic.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/it821x.c
drivers/ide/jmicron.c
drivers/ide/ns87415.c
drivers/ide/opti621.c
drivers/ide/pdc202xx_new.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/serverworks.c
drivers/ide/setup-pci.c
drivers/ide/siimage.c
drivers/ide/sis5513.c
drivers/ide/sl82c105.c
drivers/ide/slc90e66.c
drivers/ide/via82cxxx.c
include/linux/ide.h
The drivers/ide/triflex.c driver was also using ide_pci_resume() callback
but it had its own definition for .suspend() as it does not want to power
off the device during suspend. Hence, disable its PM explicitly inside
triflex_init_one() as "dev->pm_caps = 0".
Compile-tested only.
