Release management
How to you as a Scrum Master come up with a release plan for a program. What do you start with (steps)
I would say that you wouldn't. A Scrum Master may, however, facilitate this so that a Product Owner and Development Team can collaborate to create and own such an artifact.

Why only the Scrum Master or even the Product Owner??
Why can't the whole Scrum Team decide together? What do you think the impact of that Transparency would be on the ability of the team to self-organize and about their committment towards successful outcomes?
What do you start with (steps)
1. Check that each and every Sprint is planned to release something. Each Sprint is an opportunity to inspect and adapt. Anything less than this constitutes an unrelease plan.
2. Check that the matter of what gets released and when is allowed to be emergent and is understood to be an evidence-based forecast.
3. Check that the Product Backlog is being used as the single source of truth for any release forecasts that are made, and that the Product Owner is accountable for this matter.
Agree with @Ian Mitchell's list but notice that he doesn't say anywhere that the Scrum Master is actually creating any of the plans. As @Tony Divel and @Steve Matthew point out, it isn't a Scrum Master's duty to create a release plan. It is a Scrum Master's duty to help educate the rest of the Scrum Team on how to plan based on continuous feedback and adaptation while employing an incremental approach to the delivery of value.
It sounds like you are confusing a Scrum Master with a Project Manager.

As a Scrum Master, I might look to help the organization and Scrum Team achieve the following:
Start with a definition of "Done", and then the Product Owner having a vision of a "Done" Increment, for which they are prepared to invest a sprint, and the goal that they hope to achieve within that sprint.
Then discuss as a Scrum Team what can be achieved within that sprint; potentially covering ideas about how and when to release to maximize the delivery of potential value, and feedback opportunities.
Then inspect and adapt, based on what happens next.
