I think user field is not related to parent-child nodes, it defines the initiator to interact with hwmod

Copy-pasted from "arch/arm/plat-omap/include/plat/omap_hwmod.h"

"indicate the initiators that use this interface to interact with the
hwmod"

And in this case, its MPU is the initiator to interact with this interface.
