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.
