mfd: lm3533: Set DMA mask
Missing coherent_dma_mask assigning triggers the following warning in
dmesg:
[ 3.287872] platform lm3533-backlight.0: DMA mask not set
Since this warning might be elevated to an error in the future, set
coherent_dma_mask to zero because both the core and cells do not utilize
DMA.
