[PATCH v3 7/7] ARM: shmobile: armadillo800eva-reference: add DMA support for MMCIF and SDHI

Add DMA bindings to SDHI and MMCIF DT nodes on armadillo800eva-reference.
Since SDHI and MMCIF devices can use any of the 3 DMAC instances on
r8a7740, we point to the DMA multiplexer node instead of a specific DMAC
DT node.
