bitbake: bitbake-layers: convert to plugin-based
This uses bb.utils.load_plugins, based on the plugin handling in recipetool and devtool in oe-core. (Bitbake rev: 5e542df9b966a99b5a5b8aa7cf6100174aff54b2) Signed-off-by: Christopher Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
