[PATCH 06/15] PM / Domains: Remove dev_irq_safe from genpd config

[Ulf Hansson]

The genpd dev_irq_safe configuration somewhat overlaps with the runtime
PM pm_runtime_irq_safe() option. Also, currently genpd don't have a
good way to deal with these device. So, until we figured out if and how
to support this in genpd, let's remove the option to configure it.
