To reviewer: please help to check whether the change here is ok, the purpose is to check that IsBerlin features are included for BSC as it assumed the Hertz to cover all Berlin features.

I think this might not be ok after all. In core/types/transaction_signing.go the function LatestSigner(config *params.ChainConfig) checks for config.BerlinBlock to determine the Signer.

Get it, thanks, so it seems simply changes in IsBerlin() can not cover all case that BerlinBlock number takes effect.
I agree that we leave Berlin Block exist in BSCChainConfig and add HertzBlock there also, and finally make they have same value assigned.
