Commit XXXXXX (dt-bindings: memory: lpddr2: Add revision-id properties)
added the properties `revision-id1` and `revision-id2` to the
"jedec,lpddr2" binding. The "jedec,lpddr3" binding already had a single
array property `revision-id` for the same purpose. For consistency
between related memory types, this patch deprecates the LPDDR2
properties and instead adds a property in the same style as for LPDDR3
to that binding.
