device property: Use tidy for_each_named_* macros
Implementing if-conditions inside for_each_x() macros requires some
thinking to avoid side effects in the calling code. Resulting code
may look somewhat awkward, and there are couple of different ways it is
usually done.
Standardizing this to one way can help making it more obvious for a code
reader and writer. The newly added for_each_if() is a way to achieve this.
Use for_each_if() to make these macros look like many others which
should in the long run help reading the code.
