Subject: [PATCH v17 04/12] PCI: portdrv: remove unnecessary pcie_port_find_service()

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@...ux.intel.com>

Since pcie_do_recovery() has been refactored to not to depend
on PCIe service driver, we no longer have any users for
pcie_port_find_service() function. So just remove it.
