ACPI: Behave uniquely based on processor declaration definition type
Associating a Local SAPIC with a processor object is dependent upon the processor object's definition type. CPUs declared as "Processor" should use the Local SAPIC's 'processor_id', and CPUs declared as "Device" should use the 'uid'. Note that for "Processor" declarations, even if a '_UID' child object exists, it has no bearing with respect to mapping Local SAPICs (see section 5.2.11.13 - Local SAPIC Structure; "Advanced Configuration and Power Interface Specification", Revision 3.0b). This patch changes the lsapic mapping logic to rely on the distinction of how the processor object was declared - the mapping can't just try both types of matches regardless of declaration type and rely on one failing as is currently being done.
