Remove now incorrect address base arithmetic, missed by
9936d6e42392f1440505dfa9df065eabd251cadf. Fixes Sparc64 boot.

...but breaks PReP boot:
ERROR: BUG caught...
BIOS execution exception
nip=0x05800000 msr=0x00002000 dar=0x00000000 dsisr=0x00000000
Stopping execution
I verified by checking out the preceding commit, applying a variation of
http://patchwork.ozlabs.org/patch/134519/ on top; that restored PReP
boot to what it used to look like.
Any insights?
If I revert this commit on HEAD instead, then the above error
disappears, too, but there's another regression with the kernel not
being able to read the hda or something.
The write access fix seems unrelated.

Sparc64 problem was that the io_base did not match what was passed to
the functions and then the calculation made the offset totally
incorrect. Could you add printfs to see what is the offset?

NVRAM_readb: 0x00000003 <= 0x00000079
NVRAM_writeb: 0x00000000 => 0x00000006
NVRAM_writeb: 0x00000001 => 0x00000000

I/O base offset is kept with PIO but removed from MMIO, which is not
consistent. Avi, could we fix this?
Alternatively there could be different handlers for MMIO and PIO, or
in this case masking the address with 0x3 could be used but I'd rather
unify the I/O handlers.
