msm: camera: uapi: Add camera subfolder
Added a camera subfolder for the UAPI headers to be located in. This prevents the camera UAPI headers from overwriting upstream kernel headers. CRs-Fixed: 2554484 Change-Id: Ie1edbfe585bbd428a6e5d1a40b438d22bd7c06c0 Signed-off-by: Karthik Jayakumar <kjayakum@codeaurora.org>
