acpi: Generate valid ACPI processor objects
The existing code generated invalid ACPI processor objects if the core number was greater than 9. The first invalid object instance was autocorrected by Linux, but subsequent instances conflicted with each other, leading to a failure to boot if more than 10 CPU cores were installed. The modified code will function with up to 99 cores.
