[PATCH] arm: dts: imx6dl: force the 'compatible' field for the uart[12345] to 'fsl, imx21-uart'.

[iw3gtf@arcor.de (Giorgio Dal Molin)]

Without this fix the imx uart kernel driver selects 'fsl,imx6q-uart' as
its compatible value and the port does not work properly.

The kind of malfunctioning I noticed was while receiving bytes from the
uart, sending out was OK.
