Lokesh,

Based on discussion on [1] - looks like #address-cells = 0 usage
is still to be resolved and needs some alignment between Andre and
Rob on where to take this (dtc fixups to handle this Vs explicit
#address-cells = 0 and increase in dtb size).

I propose we drop this patch rather than having to revert this at a
later point after I send a PR. Anyone has any objections?
