mmc: sdhci-msm: Do not enable preset value
If preset value (bit 15) is enabled in sdhci host control2
register (0x3E), then the preset value registers(0x6F-0x60)
would be used for some of the settings such as clock and
drive strength. These are HW initialized registers and are
not properly initialized by MSM SDHCI controller. This is
resulting in low throughput for some of the modes such as
DDR50/SDR50. Hence, do not enable it for MSM SDHCI.
