i2c: kempld: Convert to use regular device PM
Provide PM callbacks through platform_driver.driver.pm instead of platform_driver.{suspend,resume} as any good-behaved driver should do. 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.
