Log Message:
pciconf(9): Configure some registers and variables for PCI-PCI bridge

Reviewed by rin@

 - Configure BARs for PCI-PCI bridge if implemented

   PCI-to-PCI Bridge Spec rev. 1.2 "3.2.5.1 Base Address registers" says
   that if the optional BARs are implemented, the configuration software
   must map address ranges.

 - Configure interrupt related registers for PCI-PCI bridge

 - Skip min_gnt/max_lat calculations for PCI-PCI bridges because those
   are not supported.

 - Handle expansion ROM base address register correctly for PCI-PCI bridges.
