I'd suggest moving this into struct sunxi_usb_phy itself, i.e. have
sunxi_usb_phy
record the phy register base, instead of the whole usb controller block, kind of
like what we have for the kernel sun4i-a10-usb-phy bindings. This
would help with
moving the phy driver to device model / DT. But it would add more modifications.
It's up to you though.

Maybe mention EHCI0 / OHCI0 are for USB OTG? Helps explain the difference.

FYI, I've some WIP patches for A83T USB, which I'll rebase. They
still need some work and testing.
