After commit b4b844930f27 ("tty: serial: fsl_lpuart: drop earlycon entry
for i.MX8QXP") earlycon support was essentially removed from
imx8qm/imx8qxp due to missing compatible.
The commit message says "i.MX8QXP lpuart is compatible with i.MX7ULP" so
adding a fallback compatible should be fine.
With this change earlycon is supported again on imx8qm/imx8qxp.
