As of commit 205e1b7f51e4 ("dma-mapping: warn when there is no
coherent_dma_mask") the Migo-R platform devices registered without a DMA
mask and coherent DMA mask issue the following warning
WARNING: CPU: 0 PID: 1 at ./include/linux/dma-mapping.h:516 0x40159e20
Set dma mask and coherent DMA mask for Migo-R platforms devices to 32
bits as all other SH4a platforms do.
