This doesn't sound like a syscon to me. Are there multiple clients or
functions in this block? A 'syscon' property is not the only way to
create a regmap if that's what you need.
It's used only by the WED code in the ethernet driver, but there are
multiple WED instances and only a single pcie-mirror block containing
configuration for them.
