mb/google/zork: Set eMMC presets
They should be tuned per board to get the best signal and boot time. This fixes the HS400 preset, so it's correctly set to A. It also changes the SDR50 and DDR50 presets to B. We can't boot correctly when DDR50 is set to A. I chose 1 as the init kHz value since that's what depthcharge uses to calculate the init clock. BUG=b:159823235 TEST=Boot Ezkinil and dump SDHCI preset registers.
