Move x86's 'struct kvm_mmu_memory_cache' to common code in anticipation
of moving the entire x86 implementation code to common KVM and reusing
it for arm64 and MIPS. Add a new architecture specific asm/kvm_types.h
to control the existence and parameters of the struct. The new header
is needed to avoid a chicken-and-egg problem with asm/kvm_host.h as all
architectures define instances of the struct in their vCPU structs.

Instead of carrying an empty include file for at least two of the
architectures
(s390 and Power), how about having it in asm-generic, and updating
arch/$ARCH/include/asm/Kbuild to point to the generic one?
Thanks,
M.
