Yes, seem that it doesn't load the reset manager driver automatically
when other driver depend on it.
Notice this issue when enable reset framework in GPIO, GPIO driver is
loaded at very beginning before go to command prompt.
Found this can work in SPL, but not in U-boot (load reset manager
driver automatically).
