drm/amdgpu: Adjust usleep_range in fence wait
[ Upstream commit 3ee1c72606bd2842f0f377fd4b118362af0323ae ]
Tune the sleep interval in the PSP fence wait loop from 10-100us to
60-100us.This adjustment results in an overall wait window of 1.2s
(60us * 20000 iterations) to 2 seconds (100us * 20000 iterations),
which guarantees that we can retrieve the correct fence value
