kvm: move KVM_CAP_NR_MEMSLOTS to common code 

All architectures except MIPS were defining it in the same way,
and memory slots are handled entirely by common code so there
is no point in keeping the definition per-architecture.

This ioctl allows the user to create, modify or delete a guest physical
