[PATCH] powerpc/eeh: make eeh_ops structures _ro_after_init

[Bhumika Goyal]

These structures are passed to the eeh_ops_register function during the
initialization phase. There they get stored in a structure variable
which only makes function calls through function pointers. There is no
other usage of these eeh_ops structures and their fields are never
modified after init phase. So, make them __ro_after_init.
