Revert "fdt: translate address if #size-cells = <0>"

This reverts commit d64b9cdc.

As pointed by [1] and [2], the reverted patch made every DT 'reg'
property translatable. What the patch was trying to fix was fixed in a
different way from previously submitted patches which instead of
correcting the generic address translation function fixed the issue with
appropriate platform code.
