PCI: endpoint: Setting a BAR size > 4 GB is invalid if 64-bit flag is not set

Setting a BAR size > 4 GB is invalid if PCI_BASE_ADDRESS_MEM_TYPE_64
flag is not set.

This sanity check is done in pci_epc_set_bar(), so that we don't need
to do this sanity check in all epc->ops->set_bar() implementations.
