lynxpoint: Fix SerialIO ACPI compile issue with recent IASL 

The SerialIO DwordIo() definition is fixed up before returning
it in the serialio device _CRS method, so the values that are set
in the raw ASL are not actually used.

However modern versions of IASL do not like that the RangeLength is
set to zero and will fail to compile.  Set this value to 1 to make
IASL stop complaining, but the real value is still fixed up in _CRS
so this has no real effect on the end result.
