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.
