v1 -> v2:
* Use label-based overriding/extension of nodes. (Doug Anderson)
* Dropped tps65090 for now, until we know where to place it.
* Dropped non-Spring nodes from -cros-common.dtsi rather than disabling them.
* Enabled a missing MMC node for access to internal storage.
* Dropped display-timings from dp-controller node. (Ajay Kumar)
