Palmer Dabbelt 44602af858 RISC-V: Allow both Zmmul and M
We got to talking about how Zmmul and M interact with each other
https://github.com/riscv/riscv-isa-manual/issues/869 , and it turns out
that QEMU's behavior is slightly wrong: having Zmmul and M is a legal
combination, it just means that the multiplication instructions are
supported even when M is disabled at runtime via misa.

This just stops overriding M from Zmmul, with that the other checks for
the multiplication instructions work as per the ISA.
