[PATCH 2/2] arm64: zynqmp: Add ifm ZynqMP VHIP6 EvalBoard

[Marek Vasut <marex@nabladev.com>]

Add support for ifm ZynqMP VHIP6 EvalBoard reference design.
The board is populated with four ethernet ports, QSPI NOR,
eMMC, UART and USB host interfaces.

NOTE: Checkpatch complains about ethernet-phy-id2000.a240 being
      undocumented, but the TI DP83822I is generic C45 PHY that
      is valided by Documentation/devicetree/bindings/net/ethernet-phy.yaml
