core/pci: Introduce separate function to initialize PCIe capability
The logic initializing device's PCIe capability is resident in the
function pci_scan_one() from day one. It's because information
(e.g. vendor/device IDs) aren't stored into PCI device instance in
old days. Now, the PCI device instance contains all information
required to initialize its PCIe capability and others.
This moves the logic initializing PCIe capability from pci_scan_one()
to separate functions, pci_init_capabilities() and pci_init_pcie_cap().
pci_scan_one() is simplified to make code maintaining a bit easier.
Also, it will allow us to intorduce separate functions to initialize other
capabilities as we're doing for PCIe capability.
This also exports pci_init_capabilities() so that it can be reused by
SRIOV VFs in future. No logical changes introduced by this.
