Subject: [PATCH] staging: ccree: 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
   3800	    488	      0	   4288	   10c0	drivers/staging/ccree/ssi_driver.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   4010	    288	      0	   4298	   10ca	drivers/staging/ccree/ssi_driver.o
