[PATCH v4 2/4] dt-bindings: clock: renesas: rcar-usb2-clock-sel: Add power-domains and resets properties

[Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>]

This patch adds missing required properties of power-domains and resets.
Fortunately, no one has this device node for now, so that we don't
need to think of backward compatibility.

Fixes: 311accb64570 ("clk: renesas: rcar-usb2-clock-sel: Add R-Car USB 2.0 clock selector PHY")
