ARM: shmobile: bockw: fixup DMA mask



4dcfa600
(ARM: DMA-API: better handing of DMA masks for coherent allocations)
exchanged DMA mask check method.
Below warning will appear without this patch

asoc-simple-card asoc-simple-card.0: \
  Coherent DMA mask 0xffffffffffffffff is larger than dma_addr_t allows
asoc-simple-card asoc-simple-card.0: \
  Driver did not use or check the return value from dma_set_coherent_mask()?
