Define "clock-<freq>" as the preferred node name for fixed-clock and fixed-factor-clock where <freq> is the output frequency of the clock. There isn't much of an existing pattern for names of these nodes. The most frequent patterns are a prefix or suffix of "clk", but there's a bunch that don't follow any sort of pattern. We could use "clock-controller-.*", but these nodes aren't really a controller in any way. So let's at least align with part of that and use 'clock-'.
For now this only serves as documentation as the schema still allows anything to avoid lots of additional warnings for something low priority to fix. Once a "no deprecated" mode is added to the tools, warnings can be enabled selectively.
