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.
