The VIRTUALIZATION symbol depends on HAVE_KVM but CONFIG_REMOTEPROC
and CONFIG_RPMSG do not select HAVE_KVM leading to the following
warning and build problems later on:
warning: (REMOTEPROC && RPMSG) selects VIRTUALIZATION which has unmet
direct dependencies (HAVE_KVM)
warning: (REMOTEPROC && RPMSG) selects VIRTUALIZATION which has unmet
direct dependencies (HAVE_KVM)

This seems odd. Usually architectures declare that they HAVE_xyz
and then drivers etc. can use that symbol to do (or not do) something.
See Documentation/kbuild/kconfig-language.txt and search for /HAVE_/.
