arm_mpam: resctrl: Implement helpers to update configuration
resctrl has two helpers for updating the configuration.
resctrl_arch_update_one() updates a single value, and is used by the
software-controller to apply feedback to the bandwidth controls, it has to
be called on one of the CPUs in the resctrl:domain.
resctrl_arch_update_domains() copies multiple staged configurations, it can
be called from anywhere.
Both helpers should update any changes to the underlying hardware.
Implement resctrl_arch_update_domains() to use
resctrl_arch_update_one(). Neither need to be called on a specific CPU as
the mpam driver will send IPIs as needed.
