[ARM/tegra] nvhost: Tuned ACM timeout.
Drastic reduction of ACM timeout to 2ms (from 1sec) resulted in power
increase for NV omxplayer video-playback (bug 738557). The reason is
that short-term scheduling does not provide enough idle time for LP2
state (CPU powered down). On the other hand, 1 sec timeout prevented
core voltage scaling during Android music audio-playback (bug 735111).
Hence, tuned ACM timeout to 25ms.
(cherry picked from commit 32c727ae2c4f91e8d7c9c261921bb62ad14217c9)
