Merge branch 'kvm-kconfig'
Cleanups to Kconfig definitions for KVM
* replace HAVE_KVM with an architecture-dependent symbol, when CONFIG_KVM
may or may not be available depending on CPU capabilities (MIPS)
* replace HAVE_KVM with IS_ENABLED(CONFIG_KVM) for host-side code that is
not part of the KVM module, so that it is completely compiled out
* factor common "select" statements in common code instead of requiring
each architecture to specify it
