npu2-opencapi: Rework link training timeout
[ Upstream commit 2600cfac4db106b219deee042f53e8d9c54d857d ]
Opencapi link state should be polled for up to 3 seconds. Current code
assumes a tight retry loop during fundamental reset at boot, which is
not going to be true on link retraining. So update the timeout
detection code to use a timebase instead of a simple retry count which
could be way too long.
