Create a new arch-specific subdirectory to contain architecture-specific code
and includes.
The Makefile now adds various arch-specific objects based on detected
architecture. That aside, this patch should only contain code moves. These
include:
- x86-specific kvm_cpu setup, kernel loading, memory setup etc. now in
x86/kvm{-cpu}.c
- BIOS now lives in x86/bios/
- ioport setup
- KVM extensions are asserted in arch-specific kvm.c now, so each architecture
can manage its own dependencies.
- Various architecture-specific #defines are moved into $(ARCH)/include/kvm{-cpu}.h
such as struct kvm_cpu, KVM_NR_CPUS, KVM_32BIT_GAP_SIZE.
