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
2673 400 0 3073 c01 power/supply/pcf50633-charger.o
File size After adding 'const':
text data bss dec hex filename
2737 336 0 3073 bed power/supply/pcf50633-charger.o
