arm: ep93xx: add dma_masks for the M2P and M2M DMA controllers

The dma_mask and coherent_dma_mask need to be set or DMA memory allocations
will fail with error messages like this:

  ep93xx-dma ep93xx-dma-m2p: coherent DMA mask is unset

  ep93xx-dma ep93xx-dma-m2m: coherent DMA mask is unset

Add the missing information to the ep93xx-dma-m2p and ep93xx-dma-m2m
devices.
