With the above commit in 4.13, for powervs platform storage is not handled, which causes cluster image-registry operator to not getting installed. 

Need to handle powervs platform here.

Options discussed are to go with pvc with CSI.

If its not feasible, will try to use IBMCOS used by satellite team.
