ARM: dts: AM437x-GP-EVM: Fix DCDC3 voltage 

On older PMICs the reset value of the DCDC3 voltage was different.
Fix DCDC3 volatge to 1.5V which is the right value to be supplied by
DCDC3 for all the production boards(Version 1.4+).

This fixes the boot hang issue during the regulator initialization stage.
