Oleksandr Tymoshenko d3d7f709ce - Add hw.bcm2835.sdhci.hs tunable to enable/disable highspeed mode in 
SDHCI driver
  Suggested by: Daisuke Aoyama

- Set initilization sequence frequency to 8MHz. It should fix Data CRC
    errors. Standard requires initialization sequence to be executed
    at 400KHz but on this hardware low frequncies seems to cause
    Data CRC errors.

    Value was derived from analyzing hardware signals after
    Raspberry Pi is powered up. Before any data is read though DATA line
    adapter's clock frequency is changed to 8MHz.

    Modern cards should function fine at 8MHz but for older MMC cards it
    can be overriden by setting hw.bcm2835.sdhci.min_freq tunable.
