After commit cb0698a ("boot-qemu.sh: Use implementation defined pointer
authentication algorithm"), using boot-qemu.sh on AArch64 hardware
fails:
$ boot-qemu.sh -a arm64 -k ...
qemu-system-aarch64: can't apply global max-arm-cpu.pauth-impdef=true: Property 'max-arm-cpu.pauth-impdef' not found
This property only applies to TCG, so it should not be applied to KVM.
In fact, none of the CPU handling that we have in the aarch64 block
applies to KVM, as '-cpu max' is implicitly treated as '-cpu host' when
'-enable-kvm' is passed. To make this explicit, add '-cpu host' to the
KVM arguments and move all the CPU handling into the non-KVM (TCG)
block.
