drm/msm/sde: Update LTM code for couple of use cases
This change removes LTM_SET_BUF and LTM_QUEUE_BUF properties from
being added to color proc active list, since those properties
don't need to be re-applied during suspend/resume or IPC.
It also fixes LTM histogram enable issue for IPC use case, skips
notifying user space with zero backlight value, and properly frees
the LTM buffers if LTM_SET_BUF property is disabled.
