fix IO Macro/Namestring name clash in iasl compiler

[Thomas Renninger]

Hi,

I got a DSDT that uses IO as an OperationRegion/Field definition.
As this seems to be working with the M$ compiler, it does not with the Intel.

This fixes/workarounds the problem (Thanks to Michael Matz for helping me to find a fix):
DSDT to test: http://www.renninger.de/acpi/dsdt.dsl
