Since the common binding 'snps,dwmac' allows selecting 'ahb' only in conjunction with 'stmmaceth', extend the logic to also permit exclusive usage of the 'ahb' reset name. This ensures the following use cases are supported: JH7110: reset-names = "stmmaceth", "ahb"; JH7100: reset-names = "ahb"; other: reset-names = "stmmaceth"; Also note the need to use a different dwmac fallback, as v5.20 applies to JH7110 only, while JH7100 relies on v3.7x.
