dt-bindings: pci: apple,pcie: Add t6020 compatible string 



t6020 adds some register ranges compared to t8103, so requires
a new compatible as well as the new PHY registers.

Thanks to Mark and Rob for their helpful suggestions in updating
the binding.

  PCIe host bridges is absent.



  On systems derived from T602x, the PHY registers are in a region

  separate from the port registers. In that case, there is one PHY

  register range per port register range.



  All root ports share a single ECAM space, but separate GPIOs are

  used to take the PCI devices on those ports out of reset.  Therefore

  the standard "reset-gpios" and "max-link-speed" properties appear on
