dt-bindings: clk: versaclock5: Add optional load capacitance property

Browse Source 
There are two registers which can set the load capacitance for
XTAL1 and XTAL2. These are optional registers when using an
external crystal.  Since XTAL1 and XTAL2 will set to the same value,
update the binding to support a single property called
xtal-load-femtofarads.
