target/xtensa: fixup test_mmuhifi_c3 overlay

xtensa-modules part of the test_mmuhifi_c3 core is missing fixes that
returns XTENSA_UNDEFINED for undefined opcodes and marks all data
structures static. Run sed script from target/xtensa/import_core.sh on
it. This fixes test_sr tests for missing special registers.
