memory: tegra: Correct debugfs clk rate-range on Tegra20
[ Upstream commit 2243af41115d0e36e6414df6dd2a0386e022d9f8 ]
Correctly set clk rate-range if number of available timings is zero.
This fixes noisy "invalid range [4294967295, 0]" error messages during
boot.
Fixes: 8209eefa3d37 ("memory: tegra: Implement EMC debugfs interface on Tegra20")
