drm/amdkfd: Cleanup IO links during KFD device removal
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.
