commit c274c9f4ea758bd6667a363f275e45275f2b5672 upstream.
pci_epf_linkup() is intended to be invoked if the EPC supports linkup
notification. Now that pci-epf-test uses the get_features() callback,
which indicates Cadence EP driver doesn't support the linkup notification,
remove pci_epf_linkup() from Cadence EP driver.
