This is similar to the socfpga case Marek pointed out.  Today, the
platforms are building with SPI support enabled and are implicitly
getting SPL_DM_SPI enabled too
http://patchwork.ozlabs.org/project/uboot/patch/20200610201634.8457-30-trini@konsulko.com/
is the Makefile patch but it's just dropping in to the DM or not-DM side
based on SPL/TPL_DM and not just DM in main U-Boot.
