I checked that the official name of this board is "VisionFive 2". The
board has version A and version B, which are different in gmac and phy
chip. The version A board has one 1000M and one 100M Ethernet ports
while the version B board has two 1000M Ethernet ports. In dts, they
have different configuration parameters for gmac. So I would like to
distinguish them by two compatibles as below in the next version.

      - items:
          - enum:
              - starfive,visionfive-2-va
              - starfive,visionfive-2-vb
          - const: starfive,jh7110

Best regards,
Hal
