reviewing the code I think we do not have any mt7986-eth reset line consumer at the
moment, since:
- mtk_eth_soc driver rely on syscon for resetting the chip writing directly in the register
in ethsys_reset()
- we do not rely on reset api in wed wo code.
I think we can just drop reset support in ethsys/wo-dlm nodes at the moment (since it
is not used in this series) and convert the driver to reset api as soon as
we have proper support in clk-mt7986-eth.c (AFAIU sam will work on it).
