Subject: [PATCH v2 17/19] dt-bindings: serial: fsl-lpuart: Fix compatible matching

The i.MX 8QXP DTSes use two compatibles so update the binding to fix
dtbs_check warnings like:

  arch/arm64/boot/dts/freescale/imx8qxp-mek.dt.yaml: serial@...60000:
    compatible: ['fsl,imx8qxp-lpuart', 'fsl,imx7ulp-lpuart'] is too long
    From schema: Documentation/devicetree/bindings/serial/fsl-lpuart.yaml

  arch/arm64/boot/dts/freescale/imx8qxp-mek.dt.yaml: serial@...60000:
    compatible: Additional items are not allowed ('fsl,imx7ulp-lpuart' was unexpected)

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
