Samin Guo 0104340a67 riscv: dts: starfive: visionfive 2: Add configuration of gmac and phy
v1.3B:
  v1.3B uses motorcomm YT8531(rgmii-id phy) x2, need delay and
  inverse configurations.
  The tx_clk of v1.3B uses an external clock and needs to be
  switched to an external clock source.

v1.2A:
  v1.2A gmac0 uses motorcomm YT8531(rgmii-id) PHY, and needs delay
  configurations.
  v1.2A gmac1 uses motorcomm YT8512(rmii) PHY, and needs to
  switch rx and rx to external clock sources.
