As we added USB0 route auto switching support for A64, add related
device tree parts to the A64 DTSI file (EHCI0/OHCI0 controllers and the
pmu0 memory area for PHY).

This breaks the older DTs, and that property isn't documented.
It's already documented.
In the H3 dual-route patchset I have already added this.
(" * "pmu0" for H3, V3s and A64")
This is not in linux-next then, sorry.
It's already in next-20160405.
P.S. to be compatible with older DTs, I think I should adjust
the phy driver, make it enable dual-route function only when
pmu0 is present.
That, or if we're quick enough, we can still add it to 4.11. There's a
bit of time left.
Thus the device tree binding patch and the DT part of this patchset
should be all pushed to 4.11 .
The device tree binding patch is commit ee73fd7dfc86 ("dt: bindings: add
pmu0 regs for USB PHYs on Allwinner H3/V3s/A64").
