[PATCH] gnumach: Remove PCI_CFG2_* as a reserved ioport range

[Damien Zammit]

PCI CONF2 access method was deprecated in PCI v2.0

Also, the conf2 ioport range is only activated for use
as pci configuration space when conf1 registers are accessed
in a particular sequence.

Since the pci-arbiter does not access the conf1 forwarding register,
we are safe to remove this completely from gnumach to allow
normal I/O use of the conf2 range as modern hardware expects.
