video: tegra: host: Improve timing of syncpt wait
nvhost_syncpt_wait_timeout() relies on sync point interrupt to
signal reaching the sync point value. With low timeout values, the
resolution is not good enough and an error is returned even when
the value is reached.
Update syncpoint value from hardware when doing a sync point wait and
do an explicit check for reaching the value even if wait returns a
timeout.
