[PATCH 02/11] arm64: dts: renesas: r8a77990: Add USB 3.0 PHY and USB3S0 clock nodes

[Marek Vasut]

This patch adds USB 3.0 PHY node for R8877990 E3 . The PHY node is
slightly different in that it does not have extal clock, which are
not routed to the SoC pads on E3. Add USB3S0 clock pad fixed-clock
node, the frequency has to be overridden at board level.
