[PATCH 27/28] mfd: tc3589x: Remove #ifdef guards for PM related functions

[Paul Cercueil]

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.

The advantage is then that these functions are now always compiled
independently of any Kconfig option, and thanks to that bugs and
regressions are easier to catch.
