cpu,nb/amd/pi/00730F01: dynamically generate CPU devices
Instead of having the maximum number of possible CPU objects defined in the DSDT, dynamically generate the number of needed CPU devices in the SSDT like it's done on all other x86 platforms in coreboot. TEST=APU2 still boots and Linux doesn't show any ACPI errors with this patch applied and it prints "ACPI: \_SB_.P000: Found 2 idle states".
