67f94b09ac4f64d4a0595d1224ba3a425e565043 target/riscv/cpu.c: consider user option with RVG
Enabling RVG will enable a set of extensions that we're not checking if
the user was okay enabling or not. And in this case we want to error
out, instead of ignoring, otherwise we will be inconsistent enabling RVG
without all its extensions.
After this patch, disabling ifencei or icsr while enabling RVG will
result in error:
$ ./build/qemu-system-riscv64 -M virt -cpu rv64,g=true,Zifencei=false --nographic
qemu-system-riscv64: RVG requires Zifencei but user set Zifencei to false
