On the R-Car Starter Kit Premier/Pro, all of the DDR0, DDR1, DDR0C, and
DDR1C power rails need 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 (SW8) is a momentary switch, hense specify
"rohm,rstbmode-pulse".
