OK, now I see more uses of this structure so the naming could be
"exynos_pm_data"?

Inlines here are mixed up and you are changing them without
explanation in commit msg. Previously the exynos_boot_vector_addr()
was inlined, now not. Okay, I can accept that but please mention this
in commit msg.
But below you are adding new inline functions which are stored as
pointers in ops. This looks both inconsistent with above and incorrect
from logical point of view. How would you like to inline them if they
are referenced through pointer? (okay, compilers are smart and crazy
so maybe they can do it but anyway I am curious how this would look
like).

ditto for the flag.
