Expose two new sysfs nodes - idle_time and idle_notify - that
are used to notify userspace whenever the display is idle with
no screen updates. The idle_time node needs to be configured
with the duration in milliseconds to detect no screen updates.
The userspace app can poll on the idle_notify node to get
notifications of the idle state.

When pipe is being detached from mixer, there is potential corner case
if underrun occurs at the same time which can cause pipe to flood the
VBIF. On the other hand unmapping a buffer requires VBIF to be idle to
sync TLB, so need to ensure pipe halt is done before freeing the pipe
buffers.
