Subject: [PATCH v2 4.19 1/7] sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra210

SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK has been set on Tegra210
ever since Tegra210 support was added to the driver in commit
b5a84ecf025a ("mmc: tegra: Add Tegra210 support").

Tegra210 SDMMC hardware by default uses timeout clock (TMCLK)
instead of SDCLK and this quirk should not be set.

So, this patch remove this quirk for Tegra210.

Fixes: b5a84ecf025a ("mmc: tegra: Add Tegra210 support")
