scsi: ibmvfc: constify dev_pm_ops structures.

dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  41937	   1296	     20	  43253	   a8f5	drivers/scsi/ibmvscsi/ibmvfc.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  42129	   1104	     20	  43253	   a8f5	drivers/scsi/ibmvscsi/ibmvfc.o
