[virtio-dev] [PATCH 03/11] transport-pci: Split notes of PCI Device Layout

[Parav Pandit <parav@nvidia.com>]

Currently single legacy interface section describes PCI common
configuration layout and feature bits operation for the
legacy interface.

Hence, split PCI Device Layout legacy interface section into two
parts. First subsection for common configuration and second
subsection for feature bits.
