This reverts commit 863fa85e. While we were testing DCN3.1 with a hub, we noticed that only one of 2 connected displays lights up when using some specific display resolution. In summary, this was the setup: 1. Displays: * Sharp LQ156M1JW26 (eDP): 1080@240 * BENQ SW320 (DP): 4k@60 * BENQ EX3203R (DP): 4k@60 2. Hub: Club3D CSV-7300 3. ASIC: DCN3.1 After bisecting this issue, we figured out the commit mentioned above introduced this issue. We are investigating why this patch introduced this regression, but we need to revert it for now.

Currently, the IO-links to the device being removed from topology, are not cleared. As a result, there would be dangling links left in the KFD topology. This patch aims to fix the following: 1. Cleanup all IO links to the device being removed. 2. Ensure that node numbering in sysfs and nodes proximity domain values are consistent after the device is removed: a. Adding a device and removing a GPU device are made mutually exclusive. b. The global proximity domain counter is no longer required to be an atomic counter. A normal 32-bit counter can be used instead. 3. Update generation_count to let user-mode know that topology has changed due to device removal.

[Why] When booting, the driver waits for the MPC idle bit to be set as part of pipe initialization. However, on some systems this occurs before OTG is enabled, and since the MPC idle bit won't be set until the vupdate signal occurs (which requires OTG to be enabled), this never happens and the wait times out.

Instead of the 'amdgpu_ring_priority_level' type, the 'amdgpu_gfx_pipe_priority' type was used, which is an error when setting ring priority. This is a minor error, but may cause problems in the future. Instead of AMDGPU_RING_PRIO_2 = 2, we can use AMDGPU_RING_PRIO_MAX = 3, but AMDGPU_RING_PRIO_2 = 2 is used for compatibility with AMDGPU_GFX_PIPE_PRIO_HIGH = 2, and not change the behavior of the code.
