[PATCH v3 20/29] arm_mpam: Allow configuration to be applied and restored during cpu online

[Shaopeng Tan (Fujitsu)]

> When CPUs come online the MSC's original configuration should be restored.
> 
> Add struct mpam_config to hold the configuration. This has a bitmap of
> features that were modified. Once the maximum partid is known, allocate a
> configuration array for each component, and reprogram each RIS configuration
> from this.
