PR24390, Don't decode mtfsb field as a cr field
"mtfsb0 4*cr7+lt" doesn't make all that much sense, but unfortunately
glibc uses just that instead of "mtfsb0 28" to clear the fpscr xe bit.
So for backwards compatibility accept cr field expressions when
assembling mtfsb operands, but disassemble to a plain number.
