Before this commit the LUT in the FCB for all i.MX RT targets had a quad-read (0xEB) command as the read command in the LUT in the FCB. However, this assumes the flash chip support QSPI, which it may not, either at all or by default. To support such flash chips this commit adds the option to use a single-read (0x03) command instead in the LUT. QSPI can then be enabled later on (by e.g. the BootROM or the application wolfBoot boots). The single-read command sequence is taken from the NXP SDK.
