Subject: drm/amdgpu: add fbdev suspend/resume on gpu reset
Git-commit: 063e768ebd27d3ec0d6908b7f8ea9b0a732b9949
Patch-mainline: v5.6-rc7
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
This can fix the baco reset failure seen on Navi10.
And this should be a low risk fix as the same sequence
is already used for system suspend/resume.
