Take advantage of the generic drvdata accessors of the generic Device
type.
While at it, use from_result() instead of match.

Implement TryFrom<&device::Device> for &Device.
This allows us to get a &pci::Device from a generic &Device in a safe
way; the conversion fails if the device' bus type does not match with
the PCI bus type.

Implement the basic PCI abstractions required to write a basic PCI
driver. This includes the following data structures:
The `pci::Driver` trait represents the interface to the driver and
provides `pci::Driver::probe` for the driver to implement.
The `pci::Device` abstraction represents a `struct pci_dev` and provides
abstractions for common functions, such as `pci::Device::set_master`.
In order to provide the PCI specific parts to a generic
`driver::Registration` the `driver::RegistrationOps` trait is implemented
by `pci::Adapter`.
`pci::DeviceId` implements PCI device IDs based on the generic
`device_id::RawDevceId` abstraction.
