This patch adds an extra operation in ns16550.c to suuport MediaTek SoCs as we have a highspeed register which influences the calcualtion of the divisor.
Note that we don't support the baudrate greater than 115200 currently.

Actually it seems to me that we should have a compatible string for this and deal with this at run-time?
Is that easy to do here?
How about this:
uart0: serial@11002000 { compatible = "ns16550a"; .... mediatek,highspeed = <0>; ....

Sorry, I didn't get it right. I will add a compatible string in ns16550_serial_ids[] for MTK chips.
