ARM: shmobile: armadillo: Fix coherent DMA mask
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.
