PCI: Unify pcie_find_root_port() and pci_find_pcie_root_port()

Browse Source 
Previously we used pcie_find_root_port() to find a Root Port from a PCIe
device and pci_find_pcie_root_port() to find a Root Port from a
Conventional PCI device.

Unify the two functions and use pcie_find_root_port() to find a Root Port
from either a Conventional PCI device or a PCIe device.  Then there is no
need to distinguish the type of the device.
