dmaengine: ste_dma40: Remove redundant address fetching function
Addresses are now stored in local data structures and are easy to obtain, thus a specialist function used to fetch them is now surplus to requirement. Signed-off-by: Lee Jones <lee.jones@linaro.org> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
