CONFIG_TIMESTAMP is not related to the RTC drivers. It does not make any sense to let the updating of the RTC by the sntp command depend on it. Drop the CONFIG_TIMESTAMP checks. Furthermore function dm_rtc_set() is enabled by CONFIG_DM_RTC. There is no reason to require CONFIG_CMD_DATE when using a driver model RTC. The UEFI sub-system can consume the RTC functions even if there is not date command. Only check CONFIG_CMD_DATE when using a non-driver model RTC.
