[PATCH 2/7] dt-bindings: Add property calxeda,pll-max-hz for Calxeda clocks

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <rob.herring@calxeda.com>

Newer versions of PLL h/w have different frequency ranges for the PLLs,
but otherwise have the same programming model. Add an optional property
"calxeda,pll-max-hz" for Calxeda PLL clocks to handle this difference.
