With the move to using binman to generate SPL aka u-boot-spl-ddr.bin and U-Boot proper aka u-boot.itb every board now covers such configuration in its own U-Boot specific device tree include. Introduce a new common imx8mm-binman.dtsi which covers the common part of that configuration.
The initial patch fixes an issue with intermediate binary naming for the imx8mm-cl-iot-gate. And subsequent patches further clean up that dtsi.
This series is based on Peng's binman conversion of late [1], my Verdin iMX8M Mini target refresh [2], Fabio's generating a single bootable flash.bin again for imx8mm-evk [3], Tim's switching imx8mm_venice to using binman to pack images [4] and Frieder's support for Kontron Electronics i.MX6UL/ULL and i.MX8MM SoMs [5].
This series has been run-time tested on Verdin iMX8M Mini. The other targets were only compile tested.
Please note that for now, I left out the following intricacies of imx8mm-venice-u-boot.dtsi. Not quite sure what exactly those are used for.

Marcell,
The of-list, @fdt-SEQ and @config-SEQ are required to support automatic generation of fdt and config nodes when you have multiple device-trees. See tools/binman/entries.rst for details.
Currently imx8mm-venice is the only imx8mm board that uses CONFIG_OF_LIST to support multiple dtbs.
