arm/dt: Tegra: Add support-8bit to SDHCI nodes
For Seaboard's internal eMMC, this makes the difference between a 5.5MB/s and 10.2MB/s transfer rate. On Harmony, there wasn't any measurable difference on my cheap/slow ~2MB/s card. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
