arm_mpam: Allow configuration to be applied and restored during cpu online
When CPUs come online the MSC's original configuration should be restored.
Add struct mpam_config to hold the configuration. For each component, this
has a bitmap of features that have been changed from the reset values. The
mpam_config is also used on RIS reset where all bits are set to ensure all
features are reset.
Once the maximum partid is known, allocate a configuration array for each
component, and reprogram each RIS configuration from this.
