As I wrote the kernel is configured CONFIG_RTC_HCTOSYS=y CONFIG_RTC_HCTOSYS_DEVICE="rtc0" so there is no module, the functionality is compiled into the kernel. And as I wrote I am using the ntp_client to set the system time via ntp/ntp_client later in the boot process to get the correct system time.
