This is more than the commit log suggests. A generic compatible by
itself is not sufficient. If other chips have the same block, just use
'qcom,ipq4019-mdio'. They should also have a compatible for the new
SoC in case it's not 'the same'.
Also, use 'enum' rather than oneOf plus const.

This breaks compatibility because now 1 entry is not valid.

These all now apply to 'qcom,ipq4019-mdio'. The h/w had no clocks or
resets and now does?
You don't need *-names when there is only 1.

This belongs in the phy node since the reset is connected to the phy.
