ARM: dts: sun7i: Add pin muxing options for clock outputs

Browse Source 
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.
