ACPI / processor: Introduce apic_id in struct processor to save parsed APIC id
For cpu hot add, we evaluate _MAT or parse MADT twice to get APIC id,
here is the code logic:
acpi_processor_add()
acpi_processor_get_info()
acpi_get_cpuid() will evaluate _MAT or parse MADT;
acpi_processor_hotadd_init()
acpi_map_lsapic() will evaluate _MAT again;
This can be done more effectively, this patch introduces apic_id in struct
processor to save parsed APIC id, and then we can use it and remove the
duplicated _MAT evaluation.
