arm64/mpam: Implement helpers for handling configuration and monitoring

hulk inclusion
category: feature
bugzilla: 34278
CVE: NA

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

So far we have accomplished resctrl resource initialization works,
we need the way to get resource(like Cache/Memory) monitor data
and apply corresponding configuration from resctrl input to MSCs.

Sometimes before applying configurations there should some necessary
operations to be pre-operated, for instance intpartid narrowing, of which
implementation is left for continuous jobs.

For monitoring, This add support to read MSMON_MBWU (QOS_L3_MBM_LOCAL
_EVENT_ID supported only) and MSMON_CSU register.

Code related to applying configuration is borrowed from http://
www.linux-arm.org/git?p=linux-jm.git;a=shortlog;h=refs/heads/mpam/
snapshot/jun, besides, monitoring related code is borrowed from Shameer's
(5cba077c "arm/mpam: Add MBWU monitor support"), please refer to link.
