sim/testsuite/cris: As applicable, require simoption --cris-900000xx

Apply the new run_sim_test option "require" as in "#require
simoption --cris-900000xx" for all tests using that option.
This allows a clean test-suite-run for a build with
--disable-sim-hardware, where that option is not supported,
by skipping those tests as "untested".
