dt-bindings: clock: ti: Add clock-output-names for TI composite clocks

For the TI composite clocks, we currently have only the divider clock
list clock-output-names as an optional devicetree property. Let's add
clock-output-names for all the TI composite clock bindings.

This allows us to use clock-output-names for the clockctrl instance name
instead of relying on a custom compatible or non-standard node names.
