[PATCH] net: freescale: gianfar : 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 <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
  19057     392       0   19449    4bf9 drivers/net/ethernet/freescale/gianfar.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  19249     192       0   19441    4bf1 drivers/net/ethernet/freescale/gianfar.o
