This patch fixes SDHCI CRC errors during of RX throughput testing on BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark value is borrowed from downstream BCMDHD driver and it's matching to the value that is already used for the BCM4339 chip, hence let's re-use it for BCM4329.
