PCI: Convert BAR sizes bitmasks to u64
PCIe r7.0, sec 7.8.6, defines resizable BAR sizes beyond the currently
supported maximum of 128TB, which will require more than u32 to store the
entire bitmask.
Convert Resizable BAR related functions to use u64 bitmask for BAR sizes to
make the typing more future-proof.
The support for the larger BAR sizes themselves is not added at this point.
