soc/amd/stoneyridge/Kconfig: Create a power restore option
File soc/amd/stoneyridge/sm.c has a CONFIG_MAINBOARD_POWER_ON_AFTER_POWER_FAIL that's not used at all and has no control. It's also not used in the build process. Remove the define from sm.c, create a true Kconfig definition and use it to define if power should be restored after a power failure/recovery. BUG=b:72873003 TEST=Build kahlee. Use serial output to check what is being programmed to RTC shadow. Build with and without selecting the Kconfig parameter. Then remove serial output and leave the parameter unselected (always S5 at power recovery).
