gpio: mxc: Improve PM configuration

Browse Source 
If CONFIG_PM=n (e.g. m68k/allmodconfig):

    drivers/gpio/gpio-mxc.c:612:12: error: ‘mxc_gpio_runtime_resume’ defined but not used [-Werror=unused-function]
      612 | static int mxc_gpio_runtime_resume(struct device *dev)
          |            ^~~~~~~~~~~~~~~~~~~~~~~
    drivers/gpio/gpio-mxc.c:602:12: error: ‘mxc_gpio_runtime_suspend’ defined but not used [-Werror=unused-function]
      602 | static int mxc_gpio_runtime_suspend(struct device *dev)
          |            ^~~~~~~~~~~~~~~~~~~~~~~~

Fix this by using the non-SET *_PM_OPS to configure the dev_pm_ops
callbacks, and by wrapping the driver.pm initializer insider pm_ptr().

As NOIRQ_SYSTEM_SLEEP_PM_OPS() uses pm_sleep_ptr() internally, the
__maybe_unused annotations for the noirq callbacks are no longer needed,
and can be removed.

Fixes: 3283d820dc ("gpio: mxc: add runtime pm support")
