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

File size before:
text data bss dec hex filename
3562 320 8 3890 f32 drivers/hwmon/i5k_amb.o

File size After adding 'const':
text data bss dec hex filename
3658 224 8 3890 f32 drivers/hwmon/i5k_amb.o

Signed-off-by: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>

Applied to hwmon-next.

Thanks,
