This patch moves all Armada 370/XP/38x/39x SPI controller nodes from the 'internal-regs' node down into the 'soc' node. This is in preparation to enable the usage of the SPI direct access mode. A follow-up patch will add the static MBus mappings for the SPI devices into the 'reg' property of the SPI controller DT node. By moving these SPI controller nodes, this patch also makes use of the labels rather than keeping the tree structure.
