[SERIAL] AMD Alchemy UART: claim memory range
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. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
