MC initialize complete signal. Setting this bit will exit the training mode of
the Integrated Memory Controller and begin normal operation including all
enabled maintenance operations. Any CHANNNEL_ACTIVE bits not set
when writing a 1 to INIT_DONE will cause the corresponding channel to be
disabled.
