Alex Deucher 9cead81eff drm/amdgpu: fix eGPU hotplug regression
The driver needs to wait for the on board firmware
to finish its initialization before probing the card.
Commit 959056982a ("drm/amdgpu: Fix discovery initialization failure during pci rescan")
switched from using msleep() to using usleep_range() which
seems to have caused init failures on some navi1x boards. Switch
back to msleep().
