No functional changes. In preparation for the auxiliary barebox build,
boot/barebox is split into two parts:
1. boot/barebox:
- The source and patch specification which are to be shared between the
barebox and barebox-aux packages.
- The barebox-package function and build logic.
2. boot/barebox/barebox:
- The package configuration, fragments, barebox env, etc.
- The actual barebox package make instantiation.
