Removing get_vm_protection_bits makes sense since those are limited to
the gmc module. I'd prefer to keep get_invalidation_req since that
protects the ip modules from a direct dependency on gmc9. We'd end up
reimplementing this when we come to an ip module that ends up being
used on a chip with a newer gmc. Also seems cleaner this way in my
opinion.
