This patch adds a macro ARCH_HAS_DMA to compile-out arch specific dma code, namely pxa_request_dma() and pxa_free_dma(). These symbols are available only in pxa, which makes impossible to build the driver in other platforms than ARCH_PXA. In order to handle non-dma capable platforms, we implement a fallbacks that allocate buffers as if 'use_dma=false', putting the dma related code under the ARCH_HAS_DMA conditional. Please note that the correct way to handle this is to migrate the dma code to use of the mmp_pdma dmaengine driver. However, currently this is not possible because the two dmaengine drivers can't work together.
