pinctrl: at91: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper

Browse Source 
Since pm.h provides a helper for system no-IRQ PM callbacks,
switch the driver to use it instead of open coded variant.

With that switch pm_ptr() to pm_sleep_ptr() as the above
mentioned callbacks are only used for system sleep.

The use of the pm_sleep_ptr() macro allows the compiler
to always see the dev_pm_ops structure and related functions,
while still allowing the unused code to be removed, without
the need for the __maybe_unused markings.
