pinctrl: intel: Provide Intel pin control wide PM ops structure

Browse source 
With the help of EXPORT_NS_GPL_DEV_PM_OPS() and
NOIRQ_SYSTEM_SLEEP_PM_OPS() we may convert PM ops functions to become
static. This also takes into account the PM configuration options such
as CONFIG_PM and CONFIG_PM_SLEEP. Hence the first step is to provide
a generic PM ops structure that can be used by drivers directly.
