kernel-yocto: move SRCREV validation to patching phase
Rather than attempting to condition the entire tree to machine SRCREV (since we don't know what branch will be built), we can instead wait until patching has completed and then confirm that we are indeed building a decendant of the specified SRCREV. The result is a much simpler check, and no mangling of the tree.
