When configuration changes are made, the new value is written to struct rdt_domain's new_ctrl field and the have_new_ctrl flag is set. Later new_ctrl is copied to hardware by a call to update_domains(). Once the CDP resources are merged, there will be one new_ctrl field in use by two struct resctrl_schema requiring a per-schema IPI to copy the value to hardware. Move new_ctrl and have_new_ctrl into a new struct resctrl_staged_config. Before the CDP resources can be merged, struct rdt_domain will need an array of these, one per type of configuration. Using the type as an index to the array will ensure that a schema configuration string can't specify the same domain twice.
