[PATCH] staging: ccree: constify dev_pm_ops structures.

[Arvind Yadav]

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

No longer applies to my staging-testing branch at all due to other
changes happening there.  Please rebase and resend.

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

File size before:
   textdata bss dec hex filename
   3800 488   0428810c0 drivers/staging/ccree/ssi_driver.o

File size After adding 'const':
   textdata bss dec hex filename
   4010 288   0429810ca drivers/staging/ccree/ssi_driver.o
