[PATCH V4 2/3] arm64: dts: tegra: Add SDMMC Auto-cal settings
Add SDMMC initial pad offsets used by auto calibration process. Add SDMMC fixed drive strengths for Tegra210, Tegra186 and Tegra194 which are used when calibration timeouts. Fixed drive strengths are based on Pre SI Analysis of the pads.
