Update FLL calculations on Arizona devices

Newer versions of the Arizona IP have several differences in the FLL configuration. The reference and synchroniser paths have slightly difference FRATIO encodings and the expanded encoding on the reference path should be used to avoid integer mode operation.

This series of patches does some refactoring on the FLL configuration code, previously calculation of the FLL configuration was done before we knew whether this would be applied to reference or synchroniser path. These patches add some checks to make sure the requested clock can be accomodated and then does the calculations once we knew where they will be applied. Additionally, we add support for the encodings on the newer IP.

Thanks,
Charles
