Subject: [PATCH 6/7] media: uvcvideo: Use MEDIA_ENT_F_GPIO for the GPIO
 entity

Right now we are setting the entity type to unknown for the privacy GPIO
entity. Which results in the following error in dmesg.
uvcvideo 3-6:1.0: Entity type for entity GPIO was not initialized!

Use the newly created type to fix this.
