5faf8b756c vmm: acpi: Add an _MAT for the CPU devices containing a LAPIC 
The Linux kernel expects all CPUs, whether they be enabled or disabled
to have an _MAT entry containing the LAPIC details for this CPU with the
enabled bit set to 1 (in the flags.)

In the MADT table the same bit is used to determine if the CPU is
present at boot vs available later.

0319a4a09a arch: vmm: Move ACPI tables creation to vmm crate 
Remove ACPI table creation from arch crate to the vmm crate simplifying
arch::configure_system()

GuestAddress(0) is used to mean no RSDP table rather than adding
complexity with a conditional argument or an Option type as it will
evaluate to a zero value which would be the default anyway.
