Subject: [PATCH 2/4] arm64: dts: imx8ulp: remove "fsl,imx7ulp-lpuart" compatible for i.MX8ULP

i.MX8ULP has specific "fsl,imx8ulp-lpuart" compatible in lpuart driver,
"fsl,imx7ulp-lpuart" compatible is no longer needed, and i.MX8ULP is not
fully compatible with i.MX7ULP, for example, i.MX8ulp can support
EOP(end-of-packet) function while i.MX7ulp doesn't, so remove
"fsl,imx7ulp-lpuart" compatible.
