hw/acpi: Update CPUs AML with cpu-(ctrl)dev change

CPUs Control device(\\_SB.PCI0) register interface for the x86 arch is IO port
based and existing CPUs AML code assumes _CRS objects would evaluate to a system
resource which describes IO Port address. But on ARM arch CPUs control
device(\\_SB.PRES) register interface is memory-mapped hence _CRS object should
evaluate to system resource which describes memory-mapped base address. Update
build CPUs AML function to accept both IO/MEMORY region spaces and accordingly
update the _CRS object.
