[PATCH] pinctrl: imx: Switch to LATE_SYSTEM_SLEEP_PM_OPS()

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

Replace SET_LATE_SYSTEM_SLEEP_PM_OPS() with its modern
LATE_SYSTEM_SLEEP_PM_OPS() alternative.

The combined usage of pm_ptr() and LATE_SYSTEM_SLEEP_PM_OPS() allows the
compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.

This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.
