U-Boot mostly uses hex for value input, largely because addresses are much easier to understand in hex. But in some cases a decimal value is requested, such as where the value is small or hex does not make sense in the context. In these cases it is sometimes useful to be able to provide a hex value in any case, if only to resolve any ambiguity. Add this functionality, for increased flexibility.
