[PATCH v5 03/12] dt-bindings: net: snps,dwmac: Add an optional resets single 'ahb'

[Samin Guo]

According to:
stmmac_platform.c: stmmac_probe_config_dt
stmmac_main.c: stmmac_dvr_probe

dwmac controller may require one (stmmaceth) or two (stmmaceth+ahb)
reset signals, and the maxItems of resets/reset-names is going to be 2.
