arm64: dts: mediatek: alias all enabled serial ports

Browse source 
On most MediaTek boards only serial0 is aliased, so the remaining
enabled uarts get first-free ttyS line numbers from the 8250 core in
probe order. When the console uart defers on its clocks another uart can
win line 0: console=ttyS0 then ends up on the wrong port and the boot
looks like a hang on the serial console, depending on probe order.
