CVS commit: src/sys/dev/pci

Module Name:    src

Modified Files:
        src/sys/dev/pci: pci.c

Log Message:
The PCI Local Bus Specification says that we should probe devices by
reading PCI_ID_REG. pci_enumerate_bus was incorrectly reading PCI_BHLC_REG
first, which surprisingly has worked for the past 16 years. Unfortunately,
this undefined behavior does the wrong thing on Amazon's Annapurna Labs
PCIe host controller.
