[igt-dev] [PATCH i-g-t 1/2] lib/intel_batchbuffer: Add bind/unbind debug for single bo for Xe

[Zbigniew Kempczyński]

We're still in early phase of integrating intel-bb infra with Xe so
debugging information about bind/unbind might be handy. Binding path
for single/multiple differs so lets add it for single case as it was
missing now.
