As long as the law applies to all religions equally, it is not a state endorsement of religion, and therefore not a violation of separation of church and state.
Now if they were to say only lift restrictions on Christian churches, or only Buddhist monasteries, then you could make a case.
Its not like out politicians are going to get any more corrupt, and I seriously doubt church money is going to compete with the mega corp money they already get. Honestly, that's probably the only reason they would list these restrictions, just a little more money in their pockets, from stupid people thinking they are making a difference.
You are ridiculously naive if you think that lifting "restrictions" for Christians will be applied equally to other religions. It doesn't even work that way now. As it stands right now the separation of Church and State barely works. Churches already endorse politicians all the time. Trump's VP comes from a red state where one of the most popular ways Republicans stay in power is to whine that "Christianity is under attack" and pass Christian favored laws. "War on Christmas" usually gets trotted out every few years.
That's not an actual endorsement from the church itself, just an endorsement from Fox News. ---
