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.

This patch cancels all the delayed_off_works if scheduled and flushes
the display threads for completion during msm_lastclose. The commit
from msm_lastclose client modeset to disable any crtcs if enabled is
always scheduled on primary crtc_commit thread. In the current issue,
delayed_off_work is scheduled on secondary display crtc_commit thread
and primary crtc_commit thread is scheduled to turn off active crtcs
from msm_lastclose leading to null dereference access of sde_enc's
cur_master. This race is avoided by serializing the operations in
msm_lastclose.

On composer kill event, drm lastclose occurs during which suspend
commit gets triggered on primary. If secondary display is stuck in
continuous splash, then we do a early return without triggering
this suspend commit. On composer start, userspace waits for power on
event, but the drm_driver has never entered suspend state, so power
on event is never sent to userspace. This causes HWC deadlock side
effect and the current change triggers null_commit on secondary
display and then issues a suspend commit on both the displays to
avoid this deadlock issue.

Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.
Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.
The differences are as follows:
1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
module (=m) or built-in (=y).
2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
Use this only when you're certain you want to do the same thing
when the config is set to module or is disabled.
