ACPI / PPTT: cacheinfo: Label caches based on fw_token

hulk inclusion
category: feature
feature: ARM MPAM support
bugzilla: 48265
CVE: NA

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

According to James's implementation: http://www.linux-arm.org/git?p=linux-


jm.git;a=commit;h=413eb4281b072e1ee60f88b814f2a418358f2155, "ACPI / PPTT:
cacheinfo: Label caches based on fw_token".

For resctrl ABI, cache node labeled by min_physid of leaf cpu node can
not be good recognized, for this, we use to label each cache node by
numa node id, it can be acquired by leaf cpu node with min_physid.

But there also has some problems when doing this, with current MPAM ACPI
Description 1.0, we haven't enough information to label those cache node
when using partition mode, we hope fixing that when getting unified des-
cription.
