ARM: tegra: power: Enable Tegra3 EMC bridge in suspend
When dvfs is suspended core rail is set to nominal voltage underneath
clock framework. On Tegra3 DDR3 platforms low EMC rates are not safe
at high voltage that exceeds EMC bridge minimum level. Enabling EMC
bridge during suspend for Tegra3 DDR3 platforms guarantees safe EMC
operations at high voltage.
