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 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.
v2: no changes
