mmc: fsl_esdhc: Fix eMMC 1.8v setting issue Current USDHC driver will reset VSELECT to 0 (3.3v) during mmc init, then set to 1 for 1.8v eMMC I/O. When booting from eMMC, since ROM has already set VSELECT to 1.8v before running the u-boot. This reset in USDHC driver causes a short 2.2v pulse on CMD pin. Fix this issue by not reset VSELECT to 0 when 1.8v flag is set. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
