pinctrl: renesas: Allow the compiler to optimize away sh_pfc_pm 

[ Upstream commit a6f06b909fee72c679c565adfa7f080f9595e336 ]

The conversion to DEFINE_NOIRQ_DEV_PM_OPS() lost the ability of the
compiler to optimize away the struct dev_pm_ops object when it is not
needed.

Fix this by replacing the use of pm_sleep_ptr() by a custom wrapper.
