disp: msm: sde: deprecate idle notify work scheduling

This change deprecates idle notify work for video mode
since idle timer will be maintained by userspace.
As part of idle notify work, syscache state is changed from
CACHE_STATE_NORMAL to CACHE_STATE_PRE_CACHE along with
notifying to the userspace. This change removes
CACHE_STATE_PRE_CACHE in the state machine and state is
updated from CACHE_STATE_NORMAL to CACHE_STATE_FRAME_WRITE
whenever the cache property is set.
