Subject: [PATCH v3 1/7] dt-bindings: timer: nuvoton,npcm7xx-timer: Allow specifying all clocks

The timer module contains multiple timers. In the WPCM450 SoC, each timer
runs off a clock can be gated individually. To model this correctly, the
timer node in the devicetree needs to take multiple clock inputs.
