drm/xe/kunit: Add stub to read_gmdid
Currently it's not possible to test the WAs for platforms using gmdid
since they don't have the IP information on the descriptor struct. In
order to allow that, add a stub function for read_gmdid() that is
activated when the test executes, replacing the iomap and read of the
real register.
