ARM: SAMSUNG: serial: Modify console initialization.

This patch modifies s3c24xx_serial_initconsole function to accept multiple
platform UART information structures. This is required on platforms that have
differences among the instances of UART ports. As an example, the FIFO sizes
could be different for each UART instance and hence multiple platform UART
information structures would be needed.

This patch also modifies the s3c24xx_console_init macro since it wraps the
call to the s3c24xx_serial_initconsole function.
