This existing code assumes that a reg property is larger than one cell, but this is not always the case. Fix this assumption.
Also if a node's parent is missing the #address-cells and #size-cells properties we use 2 as a default for each. But this should not happen in practice. More likely the properties were removed for SPL due to there being no 'u-boot,dm-pre-reloc' property, or similar. Add a warning for this as the failure can be very confusing.

Applied to u-boot-dm, thanks!
