mmc: tegra: Non std freq tuning support
Tegra sdmmc controllers support fixed sampling
frequency tuning. Also, frequency tuning is used
to find the ideal tap delay value which ensures
reliable high speed data transfers. Added support
for the same. In SDR50 mode, setting controller clk
rate to 208MHz as lower clk rates result in CRC
errors.
