This patchs uses a loongson_uart_base variable instead of the
uart_base[] array and adds a new kernel option to avoid to compile
uart_base.c all the time, which will save a little bit of memory for us.

Kernel support for this machine is almost the same as Fuloong 2F; the only
difference is that it uses the serial port provided by Loongson 2F processor
as Yeeloong 2F does.

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.

This patch add serial port support for all of the existing loongson
family machines. most of the board specific part are put in serial.c,
and the base address of the serial ports are defined as macros in
machine.h for sharing it between serial.c and early_printk.c
