imx: imx8mq: handle ESDHC in mxc_get_clock
fsl_esdhc_imx driver will call "mxc_get_clock(MXC_ESDHC_CLK + dev->seq)", however mxc_get_clock wrongly handle MXC_ESDHC_CLK as root clk and cause sd card could not be detected in U-Boot proper, as below: "Loading Environment from MMC... unable to select a mode" Handle MXC_ESDHC_CLK in mxc_get_clock to fix the issue.
