[ARM] 5276/1: ep93xx: allow selecting UART for early kernel messages
Currently on the EP93xx platform early kernel messages go to UART1. Since this UART is the only one that has modem control signals it might be used for another purpose and it is undesirable for those messages to appear. This patch allows one of the other UARTs to be selected in the kernel configuration. It is assumed that the bootloader has configured and initialized the UART since this was the previous assumption.
