Subject: [PATCH V6 02/10] PCI: Replace magic constant for PCI Sig Vendor ID

From: Ira Weiny <ira.weiny@intel.com>

Based on Bjorn's suggestion[1], now that the PCI Sig Vendor ID is
defined the define should be used in pci_bus_crs_vendor_id() rather than
the hard coded magic value.

Replace the magic value in pci_bus_crs_vendor_id() with
PCI_VENDOR_ID_PCI_SIG.
