kvx: gas: fix the detection of negative powers of 2
The detection of negative powers of 2 was wrong and could lead to
well-formed bundles ending up taking more syllables than necessary.
gas/ChangeLog:
* config/kvx-parse.c (get_token_class): Use the signed value.
* testsuite/gas/kvx/np2-detection.d: New test.
* testsuite/gas/kvx/np2-detection.s: New test.
