dts: bindings: trivial clock bindings doc fixes

fix a typo in the "clock specifiers" discussion,
clarify that clock specifiers (the integer cells
part that goes with the phandle) may be empty

@ -5,7 +5,7 @@ Sources of clock signal can be represented by any node in the device
tree. Those nodes are designated as clock providers. Clock consumer
nodes use a phandle and clock specifier pair to connect clock provider
outputs to clock inputs. Similar to the gpio specifiers, a clock
specifier is an array of one more more cells identifying the clock
specifier is an array of zero, one or more cells identifying the clock
output on a device. The length of a clock specifier is defined by the
value of a #clock-cells property in the clock provider node.
