This seems awfully specific to some SoC version, and not aware of
IRQ domains. It also seems to be only used in a dev_dbg statement,
so I guess you could just kill this off entirely.

This is wrong on a number of levels. I suspect what you really want
is an interface exported from drivers/remoteproc that looks up
a 'struct rproc' and performs the necessary reference counting.
That one can just use of_find_node_by_phandle() to get to
a device_node and use that to look up the rproc device in
a linked list it maintains.
