mfd: stmfx: Remove #ifdef guards for PM related functions
Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions 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.
