The lradc's analog reference voltage is set to 3.0 volt in the
hardware. This is more or less set in copper for at least lradc0. Set the
property in the dts to ensure the lradc is referenced properly.

I'm not sure why that patch is part of this series, but I applied
it. Thanks!

Please help fix up the subject. Should read

"ARM: dts: sun7i: set proper lradc vref on OLinuXino Lime2"

or

"ARM: dts: sun7i: olinoxino-lime2: set proper lradc vref"
