linux/configs: Rework the rtc feature

* Enable RTC devices by default with the board-commong fragment, however
  disable the HCTOSYS and SYSTOHC configs
* The rtc feature enables the HCTOSYS and SYSTOHC so that the kernel can
  manage time with the rtc for systems that explicitly have rtc
  functionality
