linux-yocto: branch manipulation changes

Richard/Saul,

Recently a few alternate workflow/use cases have been looked at recently. While they aren't existing cases, or ones that were previously supported, they are reasonable so I've tweaked the tools and processing to support them.

The first change is to allow AUTOREV processing to skip branch validation (since it doesn't make sense). The second change allows a repository with only a single BSP branch and a meta directory to be present .. and the tools can reconstruct what they need to validate and build the kernel.

Tested against the new use cases, and existing ones, all performed properly.

Pull URL: git://git.pokylinux.org/poky-contrib.git
Branch: zedd/kernel

Thanks,

linux-yocto: detect and avoid branch revision checking for AUTOREV

When a BSP or layer specifies an AUTOREV for SRCREV, the logic that matches expected vs real branch heads doesn't apply. We always want the latest.

To solve the issues with invalid git revs causing validation failures, we detect the AUTOINC value and do a early return, skipping validation.
