[PATCH] AMD Alchemy UART: claim memory range

[PATCH] AMD Alchemy UART: claim memory range

Resending since there was no reaction since the initial mail (4/4/2006)...

I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c)
doesn't claim UART memory ranges and uses wrong (KSEG1-based) UART addresses
instead of the physical ones.

WBR, Sergei
