target-ppc: PowerPC 440EP SoC emulation

Wire up the system-on-chip devices present on 440EP chips.

This patch is a little unusual in that qemu doesn't actually emulate the 440
core, but we use this board code with KVM (which does). If/when 440 core
emulation is supported, the kvm_enabled() hack can be removed.
