The LicheeRV Nano configuration disables board_init(), so the existing CV1800B sysreset driver is never bound. This is an existing board issue exposed while validating the upstream SG2002 devicetree conversion.
SG2002 uses the same RTC system reset registers as CV1800B. Enable board-specific initialization and bind the driver in board_init(), following the approach used by Milk-V Duo.
