arm64: tegra: Add missing timeout clock to Tegra210 SDMMC
commit 679f71fa0db2d777f39c7a5af7f7c0689fc713fa upstream.
commit 742af7e7a0a1 ("arm64: tegra: Add Tegra210 support")
Tegra210 uses separate SDMMC_LEGACY_TM clock for data timeout and
this clock is not enabled currently 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.
