'struct mobiveil_rp_ops' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   4446	    336	     32	   4814	   12ce	drivers/pci/controller/mobiveil/pcie-layerscape-gen4.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   4454	    328	     32	   4814	   12ce	drivers/pci/controller/mobiveil/pcie-layerscape-gen4.o

Applied to controller/layerscape, thank you!
