ARM: dts: at91: sama5d2_xplained: Add proper regulator states for suspend-to-mem
When entering suspend-to-mem, all PMIC outputs are disabled except
VDDIODDR which is put in power saving mode, and whose voltage is
increased (probably to counter the poor accuracy of power saving mode).

[claudiu.beznea@microchip.com: use regulator-changeable-in-suspend,
regulator-suspend-max-microvolt, regulator-suspend-max-microvolt,
use macros for regulators' states, add regulator-inital-state]
