From: Luke Wang <ziniu.wang_1@xxxxxxx> imx93-11x11-evk dts use the strongest driver strength for default(high-speed), 100MHz(SDR50/DDR50/DDR52) and 200MHz(SDR104/HS200/HS400) timing. To make usdhc working appropriately for each timing, add X1 drive strength to default timing and X3 drive strength to 100MHz timing.
