feature: ARM MPAM support
bugzilla: 48265
CVE: NA

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

Renaming mpam_late_init() in arch/arm64/kernel/mpam.c to mpam_init(),
traveling each MPAM ACPI cache / memory node and adding them to a list,
with that, we use the numa node id it belongs to label cache node and
proximity_domain to label memory node, once it ends, call mpam_init()
to initialize all like before.

Code was partially borrowed from James's:
http://www.linux-arm.org/git?p=linux-jm.git;a=commit;h=10fe7d6363ae96b
25f584d4a91f9d0f2fd5faf3b,"ACPI / MPAM: Parse the (draft) MPAM table
[dead]"

v3->v5: mpam.c in drivers/acpi/arm64 should not be compiled when MPAM
disabled, so we should add CONFIG_ACPI_MPAM macro and make CONFIG_MPAM
select it. Not only that, as mpam init procedure is strong correlated to
ACPI for Now (follow-up might be dependent on device tree), and CONFIG_
ACPI is not always selected under configuration, we should make CONFIG_
MPAM depends on CONFIG_ACPI before selecting CONFIG_ACPI_MPAM.
