dma-mapping: remove the dma_declare_coherent_memory export
dma_declare_coherent_memory is something that the platform setup code
(which pretty much means the device tree these days) need to do so that
drivers can use the memory as declared by the platform. Drivers
themselves have no business calling this function.
