platform/x86: tc1100-wmi: Constify static attribute_group struct

The only use of tc1100_attribute_group is to pass its address to
sysfs_create_group() and sysfs_remove_group(), both which takes pointer
to const attribute_group structs. Make it const to allow the compiler to
put it in read-only memory.
