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.

   text    data     bss     dec     hex filename
  19249     192       0   19441    4bf1 drivers/net/ethernet/freescale/gianfar.o
