Subject: [PATCH 20/22] arm64: dts: imx8qxp: Remove i.MX7 compatible from UART

The UART on i.MX 8QXP has its own compatible described in bindings
and used in the driver (with its own quirks).  Remove additional
fsl,imx7ulp-lpuart compatible 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)
