powerpc: declare unmodified attribute_group usages const
Inspired by (bd75b4ef4977: Constify static attribute_group structs),
accepted by linux-next, reported:
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20220210202805.7750-4-rikard.falkeborn@gmail.com/
Nearly all singletons of type struct attribute_group are never modified,
and so are candidates for being const. Declare them as const.
