All my boards now use early_serial_setup() instead of a platform header
file. This approach is simple to write, and requires no modifications
outside the platform_setup.c file. I'd rather not go back to providing
platform specific serial definitions in a header file.

I have just realized again that this is not possible if the serial
driver is built as a module, since you don't get the chance to call
early_serial_init between when it is loaded and when rs_init (which is
the module init function) is called.
