On Salvator-X(S), 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 (SW23) is a toggle switch, hense specify
"rohm,rstbmode-level".

  Why not 0xf if those are all bit flags?

Hi Geert,

could you address this feedback when you have some time?
