overlay: Allow disabling secure playback

Browse Source 
If the device's kernel isn't fully prepared for secure content
playback, having the secure field in the msm_rotator_img_info
struct will cause issues while playing out video.

The correct set of patches to the kernel (MDP, maybe vidc) needs
to be figured out for this to be enabled; to disable it,
add QCOM_NO_SECURE_PLAYBACK to the device's CFLAGS. (and remove
"secure" from msm_rotator_img_info)
