[PATCH 11/23] i2c: kempld: Remove #ifdef guards for PM related functions

[Paul Cercueil]

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.

Note that the driver should most likely be updated to use the
platform_driver.driver.pm.{suspend,resume} callbacks.
