PATCH 1/1 ARM: tegra: fix Jetson TK1 SD card supply

From: Stephen Warren <[email protected]>

Regulator vddio_sdmmc3 provides the Tegra<->SD IO voltage, not the card core supply voltage. That is, it provides vqmmc, not vmmc. Fix the DT to correctly reflect this.

I've applied this to Tegra's for-3.16/dt branch.
