[PATCH v2] ARM: tegra: roth: add display DT node

[Alexandre Courbot <acourbot@nvidia.com>]

DSI support has been fixed to support continuous clock behavior that the
panel used on SHIELD requires, so finally add its device tree node since
it is functional.

Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>

Changes since v1:
- Removed unneeded regulator-always-on property for vdd_lcd regulator
Only patch 4/4 of the original series has been resent for this v2.
