This is prescribing driver details to the system-management node. The
reset-controller node should be removed, the #reset-cells moved up one
level, and the "nuvoton,ma35d1-sys" should match a driver that registers
an auxiliary device for reset functionality. Is anything besides child
nodes like 'reset-controller' using the syscon@...60000?
