sf: Fix sf read for memory-mapped SPI flashes
Missing return after memcpy is done for memory-mapped SPI flashes, hence added retun 0 after memcpy done. The return is missing in below patch "sf: Enable FDT-based configuration and memory mapping" (sha1: bb8215f437a7c948eec82a6abe754c226978bd6d) Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Acked-by: Simon Glass <sjg@chromium.org>
