Subject: [PATCH v1 2/2] riscv: dts: starfive: jh7110-pine64-star64: enable USB 3.0 port

One of four USB-A ports on the Pine64 Star64 is USB 3.0 which requires to
disable PCIE0 and change the mode of PCIE0 PHY to USB3.0 operation. The
remaining three USB-A ports are USB 2.0 with the USB0 PHY and do not
conflict with any of PCIE0 or PCIE1. PCIE1 (1-lane) routes to a PCIe X4
connector.
