[libvirt] [PATCH] AArch64: Porting of armv7l conditons to run qemu for aarch64.

[Pranavkumar Sawargaonkar]

AArch64 qemu has similar behavior as armv7l, like use of mmio etc.
This patch adds similar bypass checks what we have for armv7l to aarch64.
E.g. we are enabling mmio transport for Nicdev.
Making addDefaultUSB and addDefaultMemballoon to false etc.
