Subject: [PATCH 1/2] irqchip/atmel-aic: remove #ifdef CONFIG_PM

Remove #ifdef CONFIG_PM around aic_suspend() function. Coding style
recommends (at chapter Conditional Compilation) to avoid using
preprocessor conditional in .c files.
gc->chip_types->chip.irq_suspend()/gc->chip_types->chip.irq_resume() is
called in irq_gc_suspend()/irq_gc_resume() which is NULL in case CONFIG_PM
is not defined. With this gc->chip_types->chip.irq_pm_shutdown is
populated all the time as it should be as irq_gc_shutdown() is not
conditioned by CONFIG_PM.
