Disable Simba PCI bridge routing code (Bug #8020).

Browse Source 
The code in hw/xfree86/os-support/bus/sparcPci.c:simbaCheckBus()
is trying to mimmick VGA routing by disabling I/O space responses
behind the Simba PCI-PCI controller.

Unfortunately, doing this also happens to disable access to the
IDE controller I/O space registers, thus crashing the system.  The
granularity of the I/O disabling in the Simba controller is not
fine enough to disable VGA without also disabling the IDE controller
registers.
