This patch adds a helper function to fetch the max clock from the voltage clock dependecy tables. Clocks above that level tend to be unstable and will require additional driver tweaks in order to work properly. This patch implemented the helper function to fetch the max clocks from the dependency tables. The following patches implement the per-asic clock filtering.
