Issue building flash.bin for imx8mq_evk

[Angus Ainslie]

Hi,

I've tested v2021.10 and "make flash.bin" still works there for 
imx8mq_evk_defconfig.

With the latest master that doesn't build any more

./"arch/arm/mach-imx/mkimage_fit_atf.sh" \
arch/arm/dts/imx8mq-evk.dtb > u-boot.its
/bin/sh: 1: ./arch/arm/mach-imx/mkimage_fit_atf.sh: not found
make: *** [Makefile:1350: u-boot.its] Error 127

This was the commit that broke it.

Are there binman updates for the imx8mq_evk ?

Thanks
Angus
