arm: tegra: enterprise: Controls for 3d barrier
Adds userspace control for 3d barrier on 3d panel found on enterprise.
Provides 2 sysfs files:
/sys/devices/nvhost/tergradc/stereo_mode
/sys/devices/nvhost/tergradc/stereo_orientation
These are used to enable/disable 3d barrier and control it's
orientation, respectively.
