mb/pcengines/apu1/bootblock.c: Add possibility to redirect output to COM2

Enable COM2 port on SuperIO if UART index is 1. This change allows
to use full RS232 COM1 port for different purposes when COM2 is selected
as main port.

TEST=flash coreboot with console on COM2 and observer output with UBS-TTL
converter connected to COM2 header on PC Engines apu1
