The USB3 IP in the H6 is organized such that the reset line affects both
the DWC3 core and the PHY. To model that, following the example of
several other platforms, wrap those nodes in a glue layer node.
The inner nodes no longer need to be disabled, since the glue layer is
disabled by default to keep it in reset.
