opcodes: blackfin: mark push/pop insns with a P6/P7 range as illegal
The push/pop multiple insn has a 3 bit field for the P register range, but only values of 0...5 are valid (P0 - P5). There is no such P6 or P7 register, so mark these insns as illegal. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
