Subject: drm/i915: Use intel_gt_pm_put_async in GuC submission path
Git-commit: e18417b48b4bcf5c2d27993ec2e7d075968a0744
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
GuC submission path can be called from an interrupt context
and so should use a worker to avoid holding a mutex.
