msm: sde: secure camera changes for v4l2 rotator
Add support for secure camera buffer handling in SDE rotator.
This change adds detaching the secure context when the buffer
with the secure camera flag is signaled and attaches the secure
context when going back to normal non securer-camera usecases.
