Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command.
