PCI: endpoint: Make epc->ops->clear_bar()/pci_epc_clear_bar() take struct *epf_bar
Make epc->ops->clear_bar()/pci_epc_clear_bar() take struct *epf_bar.
This is needed so that epc->ops->clear_bar() can clear the BAR pair,
if the BAR is 64-bits wide.
This also makes it possible for pci_epc_clear_bar() to sanity check
the flags.
