[PATCH 1/2] arm64: dts: mediatek: alias all enabled serial ports on Genio boards

[Carlo Caione]

Only serial0 is aliased, so the remaining enabled uarts get first-free
line numbers. When the console uart defers on its clocks, another uart
can win line 0: console=ttyS0 then ends up on the wrong connector and
the boot looks like a hang on the serial console, depending on probe
order. Alias every enabled uart so line numbers are stable.
