PCI: endpoint: Make epc->ops->clear_bar()/pci_epc_clear_bar() take struct *epf_bar

Browse Source 
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.
