console: console handover to preferred console
for earlyprintk=ttyS0,9600 console=tty0 console=ttyS0,9600n8 the handover will happen from earlyser0 to tty0. but what we want is to hand over to ttyS0. Later with serial-convert-early_uart-to-earlycon-for-8250.patch, console=tty0 console=uart8250,io,0x3f8,9600n8 will handover to ttyS0 instead of tty0.
