drm/amdgpu: Create a debug option to disable ring reset
Prior to the addition of ring reset, the debug option
`debug_disable_soft_recovery` could be used to force a full device
reset. Now that we have ring reset, create a debug option to disable
them in amdgpu, forcing the driver to go with the full device
reset path again when both options are combined.
This option is useful for testing and debugging purposes when one wants
to test the full reset from userspace.
