arm64: dts: renesas: ebisu: Add PMIC DDR0 Backup Power config
On Ebisu the DDR0 power rail needs to be kept powered when backup mode is
enabled. Reflect this in the "rohm,ddr-backup-power" property for the
BD9571MWV PMIC node.
The accessory power switch (SW23) is a toggle switch, hence specify
"rohm,rstbmode-level".
Based on advice from Geert Uytterhoeven.
