ide: add ->set_irq method
Add ->set_irq method for setting nIEN bit of ATA Device Control
register and use it instead of ide_set_irq().
While at it:
* Use ->set_irq in init_irq() and do_reset1().
* Don't use HWIF() macro in ide_check_pm_state().
There should be no functional changes caused by this patch.
