This patch adds the static MBus mappings for all supported SPI devices (8 per controller) for the direct access SPI mode. They can be configured and enabled by setting these MBus mapping in the 'ranges' property of the per-board 'soc' node. If nothing is changed here, the default 'normal' (indirect) SPI mode is used.
