Use the DEFINE_RUNTIME_DEV_PM_OPS(), SYSTEM_SLEEP_PM_OPS(),
RUNTIME_PM_OPS() and pm_ptr() macros to handle the runtime and suspend
PM callbacks.
These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_PM 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.
