Subject: ARM: dts: at91: sama5d3_xplained: not all ADC channels are available

From: Ludovic Desroches <ludovic.desroches@microchip.com>

commit d3df1ec06353e51fc44563d2e7e18d42811af290 upstream.

Remove ADC channels that are not available by default on the sama5d3_xplained
board (resistor not populated) in order to not create confusion.
