[XENBUS PATCH v6 10/11] Enable Xenbus precedence

["Tu Dinh" <ngoc-tu.dinh@xxxxxxxxxx>]

Define precedence values based on each device's numeric device ID.

This ensures that vendor devices always get activated instead of the
generic ones.

Condition the precedence on the FORCE_ACTIVATE environment variable.
