ARM: shmobile: mackerel: Fix coherent DMA mask
commit b6328a6b7ba57fc84c38248f6f0e387e1170f1a8 upstream. Commit 4dcfa60071b3d23f0181f27d8519f12e37cefbb9 ("ARM: DMA-API: better handing of DMA masks for coherent allocations") added an additional check to the coherent DMA mask that results in an error when the mask is larger than what dma_addr_t can address. Set the LCDC coherent DMA mask to DMA_BIT_MASK(32) instead of ~0 to fix the problem.
