Introduce vsync count variable in virtual encoder structure
to keep the vsync count variable value in sync while performing
the poms. Consequently, this prevents the blocking of
drm_vblank_put and the invocation of

While transition from very low fps (1Hz) to higher fps (120Hz)
there will be a delay on first frame to take effect on
mode switch. In such cases if kickoff_timeout value is programmed
based on newer high fps wr_ptr_timeout can happen. To avoid this
update the kickoff timeout with respect to lower fps and reset
it back according to present fps once the mode switch commit is
done.

MDSS INTF HW block does not generate vsync if controller
turns off the link clock prematurely. This leads to
frame trigger timeout and SDE driver triggers the retire
fence after 84ms to recover gracefully. A client may switch
source pipe from one CTL path to another CTL path based
on delayed retire fence. It can lead to other ctl path
hang. This can be resolved by resetting the lm blend

Delayed work items may touch HW registers. If these work items
run while HW is not owned by this VM it will lead to invalid
access. This happens in video mode as HAL does not disable idle
power-collapse in this mode. It can also happen with ESD status
if lastclose or TUI transition failure occurs.
Although there is a contract with user mode to turn off certain
features, kernel cannot rely on it to always do the right thing.
Prevent potential crashes from certain corner cases by
cancelling all delayed work items when the HW ownership is
