mmc: tegra: properly disable card clock
commit 3491b69045b1926a198ba70dc1296ca253f2fbdd upstream.
The new code to do the clock rate setting externally to the SDMMC
module has a shortcut to not propagate changes with a 0 rate to
the CAR by simply bailing out. This breaks proper cutting of the
card clock. Fix it by directly calling the correct sdhci function.
