Support for VMWare Workstation 6.x

Browse Source 
VMWare Workstation 6.x would previously die when running MINIX 3 with an
IOSPACE assertion and several error messages about multiply registered
I/O ports. The assertion is triggered when we probe for BAR sizes in
record_bar(). The solution: The PCI driver now disables I/O and mem
access before probing for BAR sizes.

Bumped up NR_PCIDEV and NR_PCIBUS, since Workstation 6.x virtualizes
more PCI buses and devices.
