Use the 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.
