lib/intel_batchbuffer: add create without relocs
There is create function with relocations, so add its counterpart without it. v3: moved down after intel_bb_create_with_relocs_and_context, added function description (Zbigniew review) v2: change to HIGH_TO_LOW allocation (Zbigniew) Signed-off-by: Kamil Konieczny <kamil.konieczny@linux.intel.com> Cc: Zbigniew Kempczyński <zbigniew.kempczynski@intel.com> Reviewed-by: Zbigniew Kempczyński <zbigniew.kempczynski@intel.com>
