From: Luke Wang <ziniu.wang_1 at nxp.com>
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.
