PCI: fold pci_calc_resource_flags() into decode_bar()
decode_bar() and pci_calc_resource_flags() both looked at the PCI BAR
type information, and it's simpler to just do it all in one place.
decode_bar() sets IORESOURCE_IO, IORESOURCE_MEM, and IORESOURCE_MEM_64
as appropriate, so res->flags contains all the information pci_bar_type
does, so we don't need to test the pci_bar_type return value.
decode_bar() used to return pci_bar_type, which we no longer need. We
can simplify it a bit by returning the struct resource flags rather than
updating them internally.
In pci_update_resource(), there's no need to decode the BAR type bits
again; we can just test for IORESOURCE_MEM_64 directly.
