[ Upstream commit 4e9679738a918d8a482ac6a2cb2bb871f094bb84 ]
Revert commit b4b844930f27 ("tty: serial: fsl_lpuart: drop earlycon entry for i.MX8QXP"), because this breaks earlycon support on imx8qm/imx8qxp. While it is true that for earlycon there is no difference between i.MX8QXP and i.MX7ULP (for now at least), there are differences regarding clocks and fixups for wakeup support. For that reason it was deemed unacceptable to add the imx7ulp compatible to device tree in order to get earlycon working again.
