[PATCH v2 03/22] i2c: brcmstb: Remove #ifdef guards for PM related functions

From: Paul Cercueil
Date: Sat Jul 22 2023 - 07:51:54 EST


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.
