ARM: tegra: roth: Mask HS200 mode support
Mask HS200 mode support for sdmmc4.
In DDR50 mode for eMMC can support max clock of 52MHz. For Tegra sdmmc
controllers, the host clock in ddr mode should be double that of the
eMMC device. Taking into consideration the dvfs tables, limiting ddr
mode clock to 51MHz to allow for lower core voltages to set even when
sdmmc4 clock is ON.
