msm: SSR: Remove useless warning

This is a warning so that developers know to add more restart
order lists to SSR when a new chip is added. This is mostly
irrelevant now because we assume either entire SoC restart on SSR
or independent restart on SSR, not group restarts. Remove this
warning as it is mostly a reminder that nobody is listening for.
