4.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jon Hunter <[email protected]> commit 7bf037d6ac4768e228e337afd7b6c6d98f947f9f upstream. SD card support for Tegra114 started failing after commit a8e326a911d3 ("mmc: tegra: implement module external clock change") was merged. This commit was part of a series to enable UHS-I modes for Tegra. To workaround this problem for now, disable UHS-I modes for Tegra114 by separating the soc data structures for Tegra114 and Tegra124 so that UHS-I is still enabled for Tegra124 but not Tegra114.
