[PATCH 2/3] arm64: dts: freescale: imx95-toradex-smarc: Enable bluetooth on lpuart5

[Franz Schnyder <fra.schnyder@gmail.com>]

From: Franz Schnyder <franz.schnyder@toradex.com>

The Toradex SMARC iMX95 uses the MAYA-W260 WiFi/Bluetooth module, which
uses the UART interface for Bluetooth.

Add the missing UART support to enable bluetooth functionality on the
MAYA-W260.

Although Documentation/devicetree/bindings/dts-coding-style.rst
recommends an empty line between status and latest property, leave it
unchanged for consistency with the rest of the file.
