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.
