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

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.

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.
