[PATCH v2 4.19 4/7] arm64: tegra: Add missing timeout clock to Tegra210 SDMMC

[Sowjanya Komatineni <skomatineni@nvidia.com>]

Tegra210 uses separate SDMMC_LEGACY_TM clock for data timeout and this
clock was not enabled when Tegra210 support was added to the driver in
commit 742af7e7a0a1 ("arm64: tegra: Add Tegra210 support") which is not
recommended.

Tegra SDMMC advertises 12Mhz as timeout clock frequency in host
capability register.

So, this clock should be kept enabled by SDMMC driver.

Fixes: 742af7e7a0a1 ("arm64: tegra: Add Tegra210 support")
