Add alias for lpuart5 so the UART gets a stable line number.
Without this alias, the lpuart driver fails:
fsl-lpuart 42590000.serial: failed to get alias id, errno -19
This prevents the Bluetooth controller connected to this UART from
working.
Fixes: 104a391bb6ff ("arm64: dts: freescale: imx95-toradex-smarc: Enable bluetooth on lpuart5")
