When booting msm8953-based devices, the following kernel message
appears:
[ 13.090800] qcom-spmi-vadc 200f000.spmi:pmic@2:adc@3100: Please define VDD channel

It turns out the pmi8950 uses same VDD and GND channels as other
Qualcomm's PMICs, so we can simply copy the channel definition from
the other Qualcomm's PMIC dtsi.
