These variables are only used in their defining file so should be static

Since the patch introducing this issue comes from irqchip tree, we must
either route this through that if they have earlier fixes set or wait
until v6.4-rc1 and send it through SoC tree. Please cc soc@kernel.org and
Marc Z and repost. It is better to be explicit and mention it is either
based on -next or mention the commit introducing the issue since it make
no sense if one has no knowledge of -next change.
