That way, if another muxing pops up for this clock, we will just need to add the new node, without modifying the one you add just there. Thanks! Maxime

This patch adds the clock output pin options on the A20. The 2 pins can output a configurable clock to be used by external modules. This is used on the CubieTruck, to supply a 32768 Hz low power clock to the onboard Wifi+BT module.
