That doesn't document that it implements the ID registers at all :-)
Does the hardware give the ID registers the same values as stock
PL011 or are the part number/designer/etc fields different?

Anyway, the right approach to this is going to be to have either
(a) a qdev device with a different name [this is how we handle
the pl061 variant in the Stellaris Luminary, for instance]
(b) qdev properties
so you can get the mx28 right.
