This commit adds a function into pci device trait, which returns the

pass acpi parameters and return value, when guest access the first page,
vm exit happens and it is trapped into crosvm, when guest access the

crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.

- Use SCI_INT in FADT as vSCI if FADT is forwarded.
- Inject vSCI if ACPI fixed power button is enabled and a power button
event is received.
- Disable MPTable generation if FADT is forwarded [1].
[1] MPTable generation in mptable.rs makes certain assumptions about
SCI which is incompatible with FADT forwarding. MADT takes
precedence over MPTable in the Linux kernel so hopefully things
