[PATCH V2 3/3] dt-bindings: serial: fsl-lpuart: add imx8ulp compatible string

[Sherry Sun]

Add imx8ulp compatible string in lpuart dt-binding, also correct the
imx93 compatible here, imx93/imx8ulp add some new features based on
imx7ulp lpuart, so need to add "fsl,imx8ulp-lpuart" for imx93 to enable
those new features.
