dwmmc: Increase retry timeout
When enable dcache on HiKey, we're running into MMC command timeouts because our retry loop is now faster than the eMMC (or an external SD card) can answer. Increase the retry count to the same as the timeout value for status reports. The real fix is obviously to not base this whole thing on a cycle counter but on real wall time, but that would be slightly more intrusive. Signed-off-by: Alexander Graf <agraf@suse.de>
