kernel-yocto: split meta data generation from patching phase
The linux-yocto kernel has a meta-data component which accompanies the
actual tree. That meta-data is processed to generate a series file that
controls the patching and configuration of the kernel.
patching and configuration are two distinct phases, so when working on
kernel configuration, it doesn't make sense to always have to re-run
the patching step just to update configuration data in the meta-series.
To allow a more granular set of tasks, we break the meta-data generation
into a separate task, which runs before do_patch. This allows the task
to be explicitly called when working on configuration, but otherwise
has no impact on the build.
