This patch limits the amount of address space claimed for Alchemy serial
ports to 0x1000. On the Au1300, ports are only 0x1000 apart, and the
registers only extend to 0x110 at most on all supported alchemy models.

I'm not sure who to send this patch to; I added Ralf Baechle because
he always takes my alchemy patches, 8250 is unmaintained and this
patch is required for adding support for a new alchemy model (this patch
gets me a working serial console on the DB1300).
