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).
