[PATCH v2 06/30] mfd: mt6397-irq: Remove #ifdef guards for PM related functions

[Paul Cercueil]

Use the new pm_sleep_ptr() macro to handle the .irq_set_wake() callback.

This macro allows the mt6397_irq_set_wake() function to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
