Added support for running an AArch32 guest on a AArch64 KVM host. Support has only been added to the QEMU machvirt machine. The addition of CPU properties specifiable from the command line were added to allow disablement of AArch64 execution state hereby forcing EL1 to be AArch32. The new CPU command line propoerty is "-aarch64" that is specified as follows:
aarch64-softmmu/qemu-system-aarch64 -M virt -cpu cortex-a57,-aarch64 ... Support also added to support uncompressed images (Image) for aarch32.
