The first patch add documentation about a new devicetree property
sdhci-cap-speed-modes-broken.

The second patch makes the sdhci use the DT binding instead of the caps
register for determining which speed modes are supported by the controller.

This RFC is an alternative to another patch[1] set I sent up.

v2:
 * Removed separate OF parsing function, relying on mmc_of_parse to be called
   before read_caps
 * Moved check of sdhci-cap-speed-modes-broken into sdhci_read_caps.
 * Added SDHCI_SUPPORT_HS400 to list of bits to clear in sdhci cap1, not sure
   that's all of the them now, but I think so.

Zach Brown (2):
  mmc: sdhci: Add device tree property sdhci-cap-speed-modes-broken
  mmc: sdhci: Ignore capability register when it comes to speeds and use
    DT     binding instead when sdhci-cap-speed-modes-broken is set.
