clk: bindings: Fix assigned-clock-rates description 

The binding uses assigned-clock-parents when it should use
assigned-clock-rates. Furthermore, the part that describes how
they relate to the assigned-clocks property is not clear about
what is related. Correct and clarify this part of the binding.

@ -138,9 +138,10 @@ Some platforms may require initial configuration of default parent clocks
and clock frequencies. Such a configuration can be specified in a device tree
node through assigned-clocks, assigned-clock-parents and assigned-clock-rates
properties. The assigned-clock-parents property should contain a list of parent
clocks in form of phandle and clock specifier pairs, the assigned-clock-parents
property the list of assigned clock frequency values - corresponding to clocks
listed in the assigned-clocks property.
clocks in the form of a phandle and clock specifier pair and the
assigned-clock-rates property should contain a list of frequencies in Hz. Both
these properties should correspond to the clocks listed in the assigned-clocks
property.
To skip setting parent or rate of a clock its corresponding entry should be
set to 0, or can be omitted if it is not followed by any non-zero entry.
