Fix DCDC3 volatge to 1.5V which is the right value to be supplied by
DCDC3 for all the boards.
Hmm so what about the comments for similar beaglebone changes
in thread "[PATCH] ARM: dts: am335x-boneblack: set dcdc1 regulator
for 1.35v ddr3"?
Hi Tony,
am335x uses TPS65917 PMIC and am43x* use TPS65218 PMIC.
The latest TPS65218 defaults to 1.5V. We see boot hangs when
there is a voltage change from 1.5V to 1.35V in case of AM43x
boards. Hence keeping it at 1.5V.
