arm64: dts: allwinner: A64: properly connect USB PHY to port 0

In recent Allwinner SoCs the first USB host controller (HCI0) shares
the first PHY with the MUSB controller. Probably to make this sharing
work, we were avoiding to declare this in the DT. This has two
shortcomings:
- U-Boot (which uses the same .dts) cannot use this port in host mode
  without a PHY linked, so we were loosing one USB port there.
- It requires the MUSB driver to be enabled and loaded, although we
  don't actually use it.

To avoid those issues, let's add this PHY link to the A64 .dtsi file.
After all PHY port 0 *is* connected to HCI0, so we should describe
it as this. Remove the part from the Pinebook DTS which already had
this property.

This makes it work in U-Boot, also improves compatiblity when no MUSB
driver is loaded (for instance in distribution installers).
