MXSCM-234 dts: imx: adjust the sd3 drive strength for 6sxscm evb
For some SD Ultra (40MB/s) the drive strength/speed settings
on the iomux ctrl pads for SD3 is not enougn causing some
error by transfering data as below:
mmcblk2: error -84 transferring data, sector 2250553, nr 151,
cmd response 0x900, card status 0x0
Updating the DSE and Speed on the pad ctrl fixes the issue.
