Add reset control support in USB glue logic. This needs to control

With the very little knowledge I have of this platform:

I see. I should make some explanation.
The dm tree for usb is the following.
glue
+-- controller (need controller-reset)
+-- controller-reset (need syscon-reset)
+-- phy
The controller needs to deassert "controller-reset" in the glue.
The glue needs to deassert "syscon-reset".
The glue node itself doesn't have "resets" property, so
the controller-reset controls "syscon-reset" instead.
This patch adds the reset control for "controller-reset".
Thank you,
