Update NVIDIA and Wi-Fi Direct trademark use

Update NVIDIA and Wi-Fi Direct trademark use

The Wi-Fi Direct trademark has been changed to a registered trademark,
and use is only required in titles and the first body instance.

NVIDIA instances have been modified based on the company guidelines
(capital letters, correct trademark symbol added to product names and
removed from instances that refer to the company, not a specific
trademarked product).

Cherry-picked from tizen_3.0

PS2: One lone trademark symbol deleted
