This used to work, since this regulator is on by default, but was broken by commit "ARM: tegra: dalmore: add TPS65090 node", since that didn't specify always-on for this regulator. In the long run, the regulators should all be hooked up to the SDHCI device nodes. However, we haven't done that for any of the Tegra boards yet, so to be consistent, this patch simply forces the regulator on, rather than hooking it up and making it work differently to other boards.
