[PATCH 05/42] remoteproc: keystone: Use devm_of_reserved_mem_device_init()

[Mukesh Ojha]

Replace the hand-rolled keystone_rproc_mem_release() devres action with
devm_of_reserved_mem_device_init(), which handles the cleanup
automatically. This removes both the wrapper function and the
devm_add_action_or_reset() call.
