Subject: drm/amdgpu: expand the context control interface with trust flag
MIME-Version: 1.0

Git-commit: 8350361d2d75882573c7d1af228d7827666e6929
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

This patch expands the context control function to support trusted flag while we
want to set command buffer in trusted mode.
