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.
