[PATCH v2 1/3] pinctrl: intel: Replace ifdeffery by pm_sleep_ptr() macro

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

Explicit ifdeffery is ugly and theoretically might be not synchronised
with the rest of functions that are assigned via pm_sleep_ptr() macro.
Replace ifdeffery by pm_sleep_ptr() macro to improve this.
