ACPI / PPTT: Find PPTT processor node by cache id

openeuler inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I77UDW


CVE: NA

--------------------------------

The MPAM table identifies caches by id, but the driver also wants to know
the processor node.

Add a helper that walks every possible cache, until it finds the one
identified by id, then return processor node.
