ACPI: Disambiguate processor declaration type
Declaring processors in ACPI namespace can be done using either a "Processor" definition or a "Device" definition (see section 8.4 - Declaring Processors; "Advanced Configuration and Power Interface Specification", Revision 3.0b). Currently the two processor declaration types are conflated. This patch disambiguates the processor declaration's definition type enabling subsequent code to behave uniquely based explicitly on the declaration's type.
