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.
