Many of the license and Intel copyright headers include the "All rights reserved" string. It is not relevant in the context of the BSD-3-Clause license that the code is released under. This patch removes those strings throughout the code (hypervisor, devicemodel and misc). Tracked-On: #7254 Signed-off-by: Geoffroy Van Cutsem <geoffroy.vancutsem@intel.com>
