Subject: [PATCH v3 0/2] arm64: dts: mt7981/openwrt-one: UART labels and console

This series makes two small updates for MT7981:

- Patch 1/2: Add stable labels (uart0, uart1, uart2) in the SoC dtsi so
  that board dts files can reference them directly.
- Patch 2/2: Update the OpenWrt One board dts to define serial0 alias,
  set chosen stdout-path, and enable uart0.

Both patches were build-tested (dtbs) and boot-tested: mainline Image+DTB
built and loaded via U-Boot on MT7981 hardware, with serial console output
verified.

Changes in v3:
- Patch 1/2: Unchanged.
- Patch 2/2: Drop disallowed 'current-speed' from uart0 per dtbs_check.
  Console baud is already specified via stdout-path.

Thanks,
Bryan
