linux-yocto: use src_patches for out of tree kernel feature support
To support larger out of tree kernel features and enhanced patching schemes,
this changeset modifies the linux-yocto patching routines to call the
recently factored out 'src_patches' routine. Using the returned list of local
URIs for all valid patches, the logic can then determine whether or not
patches can be used in place, or need to be migrated and have re-usable
kernel features created. The results are then fed to the existing
infrastructure to be applied and commited to the tree.
