MA35D1 EMMC出错问题

修改drive strength ==> clock/command/data分别设置为 7/0/0，即按如下设置dts：

sdhci1 {

        pinctrl_sdhci1_3_3V: sdhci1_3_3Vgrp{

            nuvoton,pins =

                <SYS_GPJ_MFPL_PJ6MFP_eMMC1_CMD &pcfg_sdhci_drive0_3_3V>,

                <SYS_GPJ_MFPL_PJ7MFP_eMMC1_CLK &pcfg_sdhci_drive7_3_3V>,

                <SYS_GPJ_MFPH_PJ8MFP_eMMC1_DAT0 &pcfg_sdhci_drive0_3_3V>,

                <SYS_GPJ_MFPH_PJ9MFP_eMMC1_DAT1 &pcfg_sdhci_drive0_3_3V>,

                <SYS_GPJ_MFPH_PJ10MFP_eMMC1_DAT2 &pcfg_sdhci_drive0_3_3V>,

                <SYS_GPJ_MFPH_PJ11MFP_eMMC1_DAT3 &pcfg_sdhci_drive0_3_3V>;

        };
