Subject: [PATCH v2 4/4] mmc: sdhci-tegra: Use actual clock rate for SW tuning correction

Ensure tegra_host member "curr_clk_rate" holds the actual clock rate
instead of requested clock rate for proper use during tuning correction
algorithm.

Fixes: ea8fc5953e8b ("mmc: tegra: update hw tuning process")
