i2c: sh_mobile: Remove dummy runtime PM callbacks
Platform drivers don't need dummy runtime PM callbacks that just return success and non-NULL pm pointer in their struct device_driver in order to have runtime PM happening. This has changed since following commits:05aa55dddb
("PM / Runtime: Lenient generic runtime pm callbacks")543f2503a9
("PM / platform_bus: Allow runtime PM by default")8b313a38ec
("PM / Platform: Use generic runtime PM callbacks directly") Signed-off-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Reviewed-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
