nit: please re-word this commit next time around to actually say what
you're doing here. I didn't notice it initially, but this patch is doing
a lot more than adding `delay_chain` configuration. To my dwmac unaware
brain, there's nothing hits for that term outside of the changelog :(

Thanks,
Conor.

Hi Conor

I suspect once we see the documentation of the binding, it will get
rejected and implemented differently. So i would not worry too much
about this at the moment.

I will re-word the commit message and add another dt-binding to describe the details that such as "rxc_dly_en","tx_inverted_10" etc.
