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.

This patch moves the platform_device setup from the various board support files into the core support file. The Ethernet driver data still remains in the individual platform setup files to allow specific platform configuration. This also adds Ethernet support to the edb9302, edb9312, and edb9315 platforms.
