[Linux-stm32] [net-next v5 2/4] dt-bindings: net: starfive, jh7110-dwmac: Add jhb100 support

[Minda Chen]

The jhb100 GMAC still using Synopsys designware GMAC core.
hardware features are similar with jh7100.

Add jhb100 GMAC compatible and reset, interrupts features.
jhb100 dwmac has only one reset signal and one interrupt
line.

jhb100 SGMII interface tx/rx mac clock is split and require to
set clock rate in 10M/100M/1000M speed. So dts need to add a
new rx clock in code, dts and dt binding doc.
