Currently Nova code uses `&'a Bar0` a lot. This is `&'a Mmio`, where `Mmio`
represents an owned MMIO region; this type only exists as a target for
`Deref` so `Bar` and `IoMem` can share code and should be avoided to be
named directly. The upcoming I/O projection series would make `Io` trait
much simpler to implement, and thus the owned MMIO type would be removed
in favour of direct `Io` implementation on `Bar` and `IoMem`.
Add lifetime parameter to `Bar0<'a>` and change it to be alias of `&'a
pci::Bar<'a, ..>`. This also prepares Nova core so that when I/O projection
series land, this could be changed to using a MMIO view type directly which
avoids double indirection.
