[PATCH 4/7] platform/x86: alienware-wmi: 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
   6932    1016      48    7996    1f3c drivers/platform/x86/alienware-wmi.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   7060     888      48    7996    1f64 drivers/platform/x86/alienware-wmi.o
