Unfortunate I failed to send this in a PR to Linus within the 4.5 rc cycle, apologize for the inconvenience! Instead I have this queued for 4.6 and I have added a stable tag to it.

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.
