clk: tegra: Implement disable_unused() of tegra_clk_sdmmc_mux_ops
[ Upstream commit 2bcc025ab9bbd029b1730cde71cb4e4f0ed35d0f ]
Implement disable_unused() callback of tegra_clk_sdmmc_mux_ops to fix
imbalanced disabling of the unused MMC clock on Tegra210 Jetson Nano.
Fixes: c592c8a28f58 ("clk: tegra: Fix refcounting of gate clocks")
