or1k: add missing l.msync, l.psync and l.psync instructions.
Even though the opcodes were defined for these instructions,
the actual instruction definitions were lacking.
cpu/
* or1korbis.cpu (l-msync, l-psync, l-csync): New instructions.
opcodes/
* or1k-desc.c, * or1k-desc.h, * or1k-opc.c, * or1k-opc.h,
* or1k-opinst.c: Regenerate.
