Let's enable KVM RISC-V in RV64 and RV32 defconfigs as module
so that it always built along with the default kernel image.

Changes since v1:
- Rebased on Linux-5.16-rc1
- Removed unwanted stuff from defconfig PATCH1
- Dropped PATCH2 and PATCH3 since these are already merged via KVM tree

I was actually just about to send a defconfig cleanup patch set. My tests are all still a bit broken, so I'm going to hold off on sending the defconfig cleanups until I can get them back together. This is so simple that anything it could break would already be broken, so I'm just going to take it now.

This is on fixes.

Thanks!
