DMA-API: others: use dma_set_coherent_mask()
The correct way for a driver to specify the coherent DMA mask is
not to directly access the field in the struct device, but to use
dma_set_coherent_mask(). Only arch and bus code should access this
member directly.
Convert all direct write accesses to using the correct API.
