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.
