Daisuke Nojiri 7e7d0be726 Fizz: Increase VR3 voltage to avoid boot failure

When V3P3A_EC is higher than V3P3A_DSW + 0.07V, system 3.3V rail
is powered by V3P3A_EC. V3P3A_EC LDO will shut down when PU27 triggers
OTP.

This patch increases VR3 voltage by 3%, which gives us 3.399.
This is more than the maximum voltage PU27 can provide, thus,
V3P3A_DSW will win the voltage race (against V3P3A_EC).
