msm: camera_v2: Import from CM kernel
msm: camera_v2: Import from Google AOSP kk_mr2 kernel

Camera drivers should match userspace.
msm: camera_v2: Create jpeg debugfs

This fixes kmsg errors because jpeg debugfs creation fails. The
device is online for only a few millisecs so the real use of the
interface is questionable, thus a full fix in ion with a camera
subdir not nessecary.

is closed. This change makes them as pr_debug messages.
