Danilo Krummrich bf9651f84b rust: pci: implement I/O mappable pci::Bar 
Implement `pci::Bar`, `pci::Device::iomap_region` and
`pci::Device::iomap_region_sized` to allow for I/O mappings of PCI BARs.

To ensure that a `pci::Bar`, and hence the I/O memory mapping, can't
out-live the PCI device, the `pci::Bar` type is always embedded into a
`Devres` container, such that the `pci::Bar` is revoked once the device
is unbound and hence the I/O mapped memory is unmapped.

A `pci::Bar` can be requested with (`pci::Device::iomap_region_sized`) or
without (`pci::Device::iomap_region`) a const generic representing the
minimal requested size of the I/O mapped memory region. In case of the
latter only runtime checked I/O reads / writes are possible.
