dts: mtmips: enable high-speed UART support for mt7628
All three UARTs of mt7628 are actually MediaTek's high-speed UARTs which
support baudrate up to 921600.
The high-speed UART is compatible with ns16550 when baudrate <= 115200.
Add compatible string to dtsi file so u-boot can use it when serial_mtk
driver is built in.
