Sixth RISC-V PR for 8.1

This is a last minute PR for RISC-V.

The main goal is to fix
https://gitlab.com/qemu-project/qemu/-/issues/1823
which is a regression that means the aclint option
cannot be enabled.

While we are here we also fixup KVM issue.

 * KVM: fix mvendorid size
 * Fixup aclint check
