video: tegra: nvavp: Add force clock stay on API
Add nvavp_force_clock_stay_on ioctl which provides way for user-mode driver
to stay on AVP clock state. This change is to fix LP0 resume fail during
Widevine playback. Since VDE/BSEV clocks are used by OTF driver in secure
world during closing sesssion, the change makes VDE/BSEV clocks running
while entering LP0.
