MLK-9872-2 arm: dts: imx6sx: add new qspi restore node
As on different boards, MQX may run on different QSPI
module, such as i.MX6SX SDB board using QSPI2, and i.MX6SX
SABREAUTO using QSPI1, so here we add a node to tell kernel
which QSPI module need to be restored after resume from
DSM mode with Mega/Fast off, by default it is for QSPI2 to
align with i.MX6SX SDB board, modify the baord dtb file to
change it.
