cacheinfo: rename of_node to fw_token
Rename and change the type of of_node to indicate it is a generic pointer which is generally only used for comparison purposes. In a later patch we will put an ACPI/PPTT token pointer in fw_token so that the code which builds the shared cpu masks can be reused.
