348a1bc30e vmm: cpu: Allocate I/O port for the CPU manager
The CPU manager uses an I/O port and to prevent potential clashes with
assignment for PCI devices ensure that it is allocated by the allocator.

07cdb37dda vmm: cpu & acpi: Query CPU manager for CPU status
Rather than hardcode the CPU status for all the CPUs instead query from
the CPU manager via the I/O port that is is on via the ACPI tables.

Each CPU device has a _STA method that calls into the CSTA method which
reads and writes the I/O ports via the PRST field which exposes the I/O
port through and OpRegion.

As we only support boot CPUS report that all the CPUs are enabled for
now.

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.
