The S5M8751 and S5M8763 MFD PMICs have no compatibles, and board file support for them was removed, resulting in essentially no way for these chips to be used anymore (unless they get dt compatibles). They seemingly have never been in any board files upstream and I only found references to the SM8751 being on the SMDK6450 board (which has been unsupported for many years now) in a downstream Samsung Galaxy S2 kernel tree. The patches should be applied in order.
