It doesn't really make sense that imx8qm and imx8dxl are backwards
compatible with imx8qxp, but only imx8qm is backwards compatible to
imx7ulp. Ir only makes sense if some feature/quirk specific to
fsl,imx7ulp-lpuart is gone in imx8qm.

Actually, I'll just drop the imx7ulp from the imx8dxl dts nodes and then
from this patch.
The imx7ulp compatible is not needed anymore because the following
commit:
b4b844930f27bf7019 ("tty: serial: fsl_lpuart: drop earlycon entry for i.MX8QXP"
got reverted by:
4e9679738a918d8a48 ('Revert "tty: serial: fsl_lpuart: drop earlycon entry for i.MX8QXP"')
Will resend with proper changes.
