arm64: dts: renesas: r8a77990: Add USB 3.0 PHY and USB3S0 clock nodes

Browse source

Add USB 3.0 PHY and PHY clock node for R-Car E3.  The PHY node is
different in that it does not have control registers and extal clock,
which are not routed to the SoC pads on R-Car E3, therefore describe the
PHY as usb-nop-xceiv simple PHY.  Add USB3S0 clock pad fixed-clock node,
the frequency has to be overridden at board level.
