fsldma: make halt behave nicely on all supported controllers
The original dma_halt() function set the CA (channel abort) bit on both the 83xx and 85xx controllers. This is incorrect on the 83xx, where this bit means TEM (transfer error mask) instead. The 83xx doesn't support channel abort, so we only do this operation on 85xx. Signed-off-by: NIra W. Snyder <iws@ovro.caltech.edu> Signed-off-by: NDan Williams <dan.j.williams@intel.com>
