Add support for booting the imxrt1050-evk from spi.
Add imximage config and the ability for SPL to boot from NOR.
Enable binman in Kconfig and device tree for imxrt* as it is used to
prepend fspi_header.bin to SPL and u-boot.img.

As a future plan do you think of moving .cfg files to within binman; you can see
