asus/am1i-a: Enable UART according to CONFIG_UART_FOR_CONSOLE
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 it. Enable UART according to
CONFIG_UART_FOR_CONSOLE - and, if UART 0 is selected, it will be initialized
at romstage and this problem will not happen.
