[PATCH] hwmon: adt7475: constify attribute_group structures.

[Arvind Yadav]

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

File size before:
   text    data     bss     dec     hex filename
  10055    7032       0   17087    42bf drivers/hwmon/adt7475.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  10567    6520       0   17087    42bf drivers/hwmon/adt7475.o
