PCI: cadence: Set PCI_BASE_ADDRESS_MEM_TYPE_64 if a 64-bit BAR was set-up
cdns_pcie_ep_set_bar() does some round-up of the BAR size, which means that a 64-bit BAR can be set-up, even when the flag PCI_BASE_ADDRESS_MEM_TYPE_64 isn't set. If a 64-bit BAR was set-up, set the flag PCI_BASE_ADDRESS_MEM_TYPE_64, so that the calling function can know what BAR width that was actually set-up. I'm not sure why cdns_pcie_ep_set_bar() doesn't obey the flag PCI_BASE_ADDRESS_MEM_TYPE_64, but I leave this for the MAINTAINER to fix, since there might be a reason why this flag is ignored.
