Use the new PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are 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.

CONFIG_PM_SLEEP are 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

Note that the behaviour is slightly different than before; the original
code wrapped the suspend/resume with #ifdef CONFIG_PM guards, which
resulted in these functions being compiled in but never used when
CONFIG_PM_SLEEP was disabled.
Now, those functions are only compiled in when CONFIG_PM_SLEEP is
enabled.

Use the new PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are 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.

Please note that this patch may still undergo further evaluation
and the final decision will be made in collaboration with
Wolfram.
