[PATCH v1 2/3] device-parts: Add device type specific raw selector

[Parav Pandit <parav@nvidia.com>]

The subsequent patch defines the device-type-specific parts. For
these parts, the raw selector format is defined to ensure that
each device type can specify its format accurately.

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/209
Signed-off-by: Parav Pandit <parav@nvidia.com>

changelog:
v0->v1:
- addressed comment from Matias
- rewrote description of selector without writing the actual
  part_type range, add description that it is device type specific
