[PATCH] Alchemy: SMBus resource fix

[Sergei Shtylyov <sshtylyov@ru.mvista.com>]

The Alchemy platform code registers the SMBus device using the virtual address
of its registers instead of the physical one -- fix this, taking into account
that actually the whole megabyte is decoded by any of the programmable serial
controllers (one of which is SMBus), and that all the Alchemy peripherals are
directly mappable into KSEG1 kernel space and therefore ioremap() call would
just boil down to CKSEG1ADDR() invocation.

I'm not sure thru which tree this should go -- probably thru Linux/MIPS one...
