Subject: [PATCH] arm64: dts: ls1028a: add flexspi nodes
Add fspi node property for LS1028A SoC for FlexSPI driver.
Property added for the FlexSPI controller and for the connected
slave device for the LS1028ARDB and LS1028AQDS target.
This is having one SPI-NOR flash device, mt35xu02g connected at
CS0.
