mmc: fsl_esdhc: Add new config option for default fallback mode
Currently default fallback SDHC mode is 1-bit. Add new config option
CONFIG_SYS_FSL_ESDHC_DEFAULT_BUS_WIDTH to allow specifying default fallback
mode. This is useful e.g. for SPL builds which loads other parts from SD
card during boot process.
