dt-bindings: memory: Add jedec,lpddr4 and jedec,lpddr5 bindings

Browse source

This patch adds bindings for LPDDR4 and LPDDR5 memory analogous to the
existing bindings for LPDDR2 and LPDDR3. For now, the new types are only
needed for topology description, so other properties like timing
parameters are omitted. They can be added later if needed.
