mmc: sdhci-of-esdhc: temporary fixup for eMMC HS400 issue
Currently only LX2160A eSDHC supports eMMC HS400. According to a large number of tests, eMMC HS400 failed to work at 150MHz, and for a few boards failed to work at 175MHz. But eMMC HS400 worked fine on 200MHz. We hadn't found the root cause but setting eSDHC_DLLCFG0[DLL_FREQ_SEL] = 0 using slow delay chain seemed to resovle this issue. Let's use this as fixup for now.
