This patch is for Starfive JHB100 EVB board. JHB100  contain
1 RGMII/RMII and 1 RMII synopsys GMAC cores. In the EVB board, RGMII
interface connect with YT8531s Ethernet PHY. RMII interface connect
with YT8522 ethernet PHY. So patch 1-2 is for RGMII interface
patch 3 is RMII is for RMII interface.

JHB100 is a Starfive new RISC-V SoC for datacenter BMC (BaseBoard
Managent Controller). Similar with Aspeed 27x0.
