Subject: [PATCH] PM / Domains: Fix compilation error for devices that don't enable PM_SLEEP

Set pm_genpd_poweroff_noirq to NULL if CONFIG_PM_SLEEP isn't enabled.
This is the same approach done for other PM_SLEEP related functions.

Without this patch building the kernel with the keystone_defconfig
results in a compilation error.

Fixes: 10da65423fdb ("PM / Domains: Call driver's noirq callbacks")
