linux-yocto/dev: linux-yocto development tree tracking recipe

The linux-yocto-dev recipe uses the upstream tracking linux-yocto-dev repository.
Since this tree is frequently updated, and periodically rebuilt, AUTOREV is used
to track its contents.

This recipe is just like other linux-yocto variants, with the only difference
being that to avoid network access during initial parsing, static SRCREVs are
provided and overridden if the preferred kernel provider is linux-yocto-dev.
