ARM: dts: am437x-sk-evm: disable DDR regulator in rtc-only/poweroff mode
Without this, the memory will remain active during poweroff consuming extra power. Please note revision 2.1 PMIC seems to fail when DCDC3 disable is attempted, so this is not done on that PMIC revision. The PMIC revision checks in the regulator patches make sure of this.
