[U-Boot] [PATCH 4/4] mmc: fsl_esdhc: drop CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT

[Peng Fan]

CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT is not the correct method
to set I/O to 1.8. To boards that does not support vqmmc-supply,
use vs18_enable in fsl_esdhc_cfg. If regulator is supported,
use fixed 1.8V regulator for vqmmc-supply.
