dtc: Convert #address-cells and #size-cells related checks This patch converts checks related to #address-cells and #size-cells to the new framework. Specifically, it reimplements the check that "reg" properties have a valid size based on the relevant #address-cells and #size-cells values. The new implementation uses the correct default value, unlike the old-style check which assumed the values were inherited by default. It also implements a new, similar test for "ranges" properties. Finally, since relying on the default values of these variables is considered not-good-practice these days, it implements a "style" check which will give a warning if the tree ever relies on the default values (that is if any node with either "reg" or "ranges" appears under a parent which has no #address-cells or #size-cells property).
