dt-bindings: mmc: tegra: Add tmclk for Tegra210 and later
commitzero-sugar-mainline-defconfigb5a84ecf02
("mmc: tegra: Add Tegra210 support") Tegra210 and later uses separate SDMMC_LEGACY_TM clock for data timeout. So, this patch adds "tmclk" to Tegra sdhci clock property in the device tree binding. Fixes:b5a84ecf02
