That feels like something that should be done with Kconfig dependencies like a direct OF dependency (possibly a !PRP0001 dependency?) for the driver or possibly with having a variant of_match_ptr() for things that really don't want to support PRP0001. Just removing all the use of of_match_ptr() is both noisy and confusing in that it looks like it's creating issues to fix, it makes it hard to understand when and why one should use the macro.
