Currently, CONFIG_RTC_SYSTOHC uses CONFIG_RTC_HCTOSYS_DEVICE which is originally used by CONFIG_RTC_HCTOSYS, but this rtc device has some limiations, for example, it must be battery-backed, be able to work with irq off and through system suspension, etc. So add CONFIG_RTC_SYSTOHC_DEVICE used exclusively for CONFIG_RTC_SYSTOHC, it is more lenient compared to CONFIG_RTC_HCTOSYS_DEVICE, and could be assigned any available RTC in the system. Default value is CONFIG_RTC_HCTOSYS_DEVICE which is "rtc0" by default. After this patch, NTP will sync up "rtc0" by default.
