[PATCH 1/2] arm64: allwinner: a64: add EHCI0/OHCI0 nodes to A64 DTSI

[Icenowy Zheng]

Allwinner A64 SoC features a pair of EHCI/OHCI controllers that can be
set to wire to USB0 port (the OTG-capable one), which can be used to
provide a better performance in host mode.

Add their device tree nodes.

[PATCH 2/2] arm64: allwinner: a64: enable EHCI0/OHCI0 for Pine64

[Icenowy Zheng]

As we have USB0 controller switch available on A64, we should now enable
the EHCI0/OHCI0 controllers for Pine64.
