This series constifies a couple of static attribute_group structs that
are not modified. This allows the compiler to put them in read-only
memory. The patches are independent and can be applied in any order (and
go through different trees if needed).

The only usage of omap_aes_attr_group is to pass its address to
sysfs_{create,remove}_group(), which takes pointers to const struct
attribute_group. Make it const to allow the compiler to put it in
read-only memory.
