asus/am1i-a: set UART_FOR_CONSOLE to 1 instead of default 0

It has been observed by me and Elisenda Cuadros / Gergely Kiss [1] that the boot process of this board is super slow when UART 0 is being used - even if nothing is connected to this port. Instead, use UART 1 by default (this board has two COM ports).

Patch Set 1: Code-Review+1

For some reason the code sets up SP2 instead of SP1, so super slow serial as a result of very high default divider is expected.

Another option is to have the romstage set up SP1 (or both)?

I would prefer the bug to be fixed. What about making sure the correct UART is initialized according to UART_FOR_CONSOLE?

I'll try to set up both SP1 and SP2 - so that, if someone switches this setting to another port, he wouldn't encounter this problem.

Very well, but which one is UART 0 and which one is UART 1? Where should one expect the logs to come […]

UART 0 = COM 1 (9 pins on-board connector), UART 1 = COM 2 (serial port connector)
