[U-Boot] [PATCH v5 01/13] m68k: add basic set of devicetrees
This patch adds a basic group of devicetrees, one for each cpu family, including actually just uart and dspi devices, since these are the drivers supporting devicetree (support added in this patch-set).

This patch removes CONFIG_SYS_DSPI_XX options from include/configs "m68k" .h board files, since CTAR registers are now set with default values in the cf_spi driver initialization, and configurable by devicetree.
Note, these options cannot be totally removed from the whitelist, since still used from boards using fsl_dspi.c (mostly arm-based boards).

This patches move dspi bus-related operations into more proper location, to avoid the driver to declares them as externs.
