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.
