Currently `devices` module cannot be solely built, by specifying
`arch/kvm` to turn on the features required for its dependency - `arch`
crate to build. Thus enabling `devices` crate to be built and tested
with command:
```sh
cargo build -p devices --features kvm

It turns out we need to setup `a0`, `pc` and `a1` for all vcpus before
we run them, remove predicates used to set `pc` and `a1` for `vcpu0`.

Previous `Vaia` implementation uses types as it is, thus the property
string generated for fdt setup requires additional type conversion.
Change the types used in the methods of `Vaia` trait to provide a
concise fdt setup process.

With 0.5.0 release of `rust-hypervisor-firmware`, `aarch64` binary were
added to assets, which causes the `FW_URL` to have multiple download url
separated by a white space, thus our integration tests would fail.
Constrain `FW_URL` to `hypervisor-fw` to resolve this.
