The DH Electronics DHCOR SOM has QSPI NOR on the SoM itself, add it into the DT.

V2: Drop the explicit flash type in DT node, use spi-flash

SPI NOR flash => 2 Mbyte boot flash
So I think that memory mapped register should be limited to 2Mbyte = 0x200000 and not 64MBytes
reg = <0x58003000 0x1000>, <0x70000000 0x200000>;
Fixed
