ARM: shmobile: bockw: fixup DMA mask
4dcfa60071b3d23f0181f27d8519f12e37cefbb9
(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()?
