Move reset manager node to top, so reset driver can be load before other drivers. Peripheral drivers have dependency on reset framework to reset the hardware.

This will break the next time you sync DTs with Linux, NAK. The reset manager should just load when it's needed by other drivers. If it doesn't work that way, something is seriously broken and that is what needs to be fixed.
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).
That's probably because you're using the reset in .bind instead of .probe , as it should be used ? .bind is ONLY for binding the driver with the DM core.
