[PATCH v2 21/27] barebox: Migrate to a bbclass

["'Jan Kiszka' via isar-users" <isar-users@googlegroups.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

"inherit barebox" is shorter and a more common pattern compared to
OE/yocto. Keep the original .inc file as transitional helper, issuing a
warning when it's used with a migration suggestion.
