Add a restructured text file describing how to write drivers

how to use the APIs that were added in the previous few

Also adds an index for the PCI documentation tree even though this
is the only PCI document that has ben converted to restructured text
at this time.

This all seems good, but...could we consider moving this documentation to
driver-api/PCI as it's converted to RST?  That would keep it together with
similar materials and bring a bit more coherence to Documentation/ as a
whole.

Thanks,
