9006013c60 hypervisor: Tune Vaia trait to work with fdt setup
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.

297236a7c0 misc: Eliminate use of assert!((...).is_ok())
Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if
the test fails, it will only say "assertion failed: false". We replace
these with `.unwrap()`, which also prints the exact error variant that
was unexpectedly encountered (we can to this these days thanks to
efforts to implement Display and Debug for our error types). If the
assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop
the assert.

Inspired by and quoted from @roypat.

88a9f79944 misc: Adapt consistent import style formatting
Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.

By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

02f146fef8 hypervisor: kvm: aarch64: fix get_device_attr() UB
DeviceFd::get_device_attr should be marked as unsafe, because it
allows writing to an arbitrary address.  I have opened a kvm-ioctls
PR[1] to fix this.  The hypervisor crate was using the function
unsafely by passing it addresses of immutable variables.  I noticed
this because an optimisation change[2] in Rust 1.80.0 caused the
kvm::aarch64::gic::tests::test_get_set_icc_regs test to start failing
when built in release mode.

To fix this, I've broken up the _access functions into _set and _get
variants, with the _get variant using a pointer to a mutable variable.
This has the side effect of making these functions a bit nicer to use,
because the caller now has no need to use references at all, for
either getting or setting.
