ARM: dts: qcom: msm8226-motorola-falcon: specify vddio_disp output voltage

Browse Source 
After some digging in downstream sources, it was found that the vddio_disp
regulator's output voltage is 1.8V. This is further confirmed by the
troubleshooting guide. Specify its output voltage as such.
While at it, add a comment specifying the IC, which according to the
schematic is the TI TPS22902.
