Patch 1 fixes the manual stop command error reporting: a successful manual stop command is still reported as failed, while a failed one stores the error in its response instead. The remaining patches improve the DMA setup and error reporting, which the UHS-I work builds upon: a DMA mask matching the shifted IDMA addresses, IDMA descriptors built from the mapped DMA segments as the DMA API requires, and CRC errors reported as -EILSEQ instead of -ETIMEDOUT, so the MMC core can request retuning. The series is based on mmc next, but depends on commit 5e32202f532d ("mmc: sunxi: fix clock and runtime PM leaks on probe failure") from mmc fixes, which adds the error_disable_mmc label used by patch 2. Tested on H3, H6 and H616 SoCs, on multiple boards, including Tanix TX6 and OrangePi Plus2E.
