arm64/mpam: Allocate mpam component configuration arrays

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

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

To bridge resctrl resources and mpam devices, we need somewhere
to store the configuration information.

We allocate a configuration array for each mpam component, which
gets configuration from intermediate structure of resctrl and write
to mpam devices(MSCs).

This config element's categories can be classified as cache ctrl
feature (CPBM and CMAX) and memory ctrl feature (MAX and PBM),
meanwhile some extended features are also supported, including
priority, and hardlimit choice,
