To share the same kernel image amon different machines we have added the machtype command line support. In the old serial port implementation the UART base address is hardcoded as a macro in machine.h which breaks with machtype, so change that to discover the address dynamically. Also move the initialization of the UART base address to uart_base.c to avoid remapping twice for early_printk.c and serial.c.
