This patchset is to add memcpy interface for imx-sdma, besides,to
support dmatest and enable config by default, so that could test dma
easily without any other device support such as uart/audio/spi...
Change from v1:
1. remove bus_width check for memcpy since only max bus width needed for
memcpy case to speedup copy.
2. remove DMATEST support patch, since DMATEST is a common memcpy case.
3. split to single patch for SDMA_BD_MAX_CNT instead of '0xffff'
4. move sdma_config_ownership() from alloc_chan into sdma_prep_memcpy.
5. address some minor review comments.
