Dynamic Capacity Devices (DCD) require event interrupts to process memory addition or removal. BIOS may have control over non-DCD event processing. DCD interrupt configuration needs to be separate from memory event interrupt configuration. Split cxl_event_config_msgnums() from irq setup in preparation for separate DCD interrupts configuration.
