x86, platform, kvm, kconfig: Turn existing .config's into KVM-capable configs
Add an config file snippet which enables additional options
useful for running the kernel in a kvm guest. When you execute
'make kvmconfig' it merges those options with an already
existing user config before you build the kernel.
Based on an patch from the external lkvm tree.
