Subject: [PATCH AUTOSEL 6.14 475/642] amdgpu/soc15: enable asic reset for dGPU in case of suspend abort

From: Jiang Liu <gerry@...ux.alibaba.com>

[ Upstream commit 38e8ca3e4b6de1c6e49d0140264cfc8d314a5f70 ]

When GPU suspend is aborted, do the same for dGPU as APU to reset
soc15 asic. Otherwise it may cause following errors:
[  547.229463] amdgpu 0001:81:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring kiq_0.2.1.0 test failed (-110)

[  555.126901] [drm:amdgpu_gfx_enable_kcq [amdgpu]] *ERROR* KCQ enable failed
[  555.126957] [drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block <gfx_v9_4_3> failed -110
[  555.126959] amdgpu 0000:0a:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
[  555.126965] PM: dpm_run_callback(): pci_pm_resume+0x0/0xe0 returns -110
[  555.126966] PM: Device 0000:0a:00.0 failed to resume async: error -110

This fix has been tested on Mi308X.
