Would it not be more straightforward to just register it as a platform
device in this case, or use a separate OF ID in the DT?  We appear to
specify a compatible string when registering AMBA devices even if we are
capable of identifying using the ID registers.

I'll drop this gpio patch for now and submit a patch on the pl022
driver instead. I read the arm,primecell binding and learned that
there is a property (arm,primecell-periphid) that can be used to
override the HW PrimeCell ID. Seems like something to use here, right?

Possibly, though if there's no hardware ID to override to that might not
be the best option.  You could always define a property that's specific
to the pl022 driver flagging that it's got these extra chip selects though.
