mb/amd: Add Pollock CRB Cereme as Mandolin variant
Even though the devicetrees of Mandolin and Cereme are relatively
similar, they are kept as separate files instead of using devicetree
overrides to facilitate creating mainboard ports based on those CRBs.
The two boards are reference boards for different zen/zen+ APU platforms
that share the silicon, but use different packages. This is also
consistent with the google/zork boards that have two different full base
devicetrees for the two different platforms and then use devicetree
overrides for the different variants of the two reference designs.
