Avoid corrupting the cb_list by setting timestamp before signal.
The fence driver changed in msm-5.4 by creating a union for the
fence cb_list, timestamp, and rcu. Therefore only one of these
fields can be used at a time. Fence driver will take care of
setting the timestamp during dma_fence_signal after it has
cached the cb_list. Also, use fence framework API to set fence
error instead of modifying the dma_fence struct directly.

dsi_display_clk_ctrl is assigned as a callback function to struct
sde_connector_ops::clk_ctrl. This changes changes the function type to
match the pointer type to avoid Control-Flow Integrity (CFI) failures.

In an effort to reset the DP controller states on a disconnect, the
driver is issuing a SW reset to the controller. But SW reset on
the controller doesn't necessarily restore the controller to its
full reset state. It only resets part of the logic. So if for some
reason the MST streams were not disabled properly, ie. the slot
allocations were not reset properly in the controller, then a SW
reset would result in the DP controller raising state interrupts.
Since this SW reset is issued in the tail end of the disconnect
processing, the driver turns off all the clocks and also
removes the irq handler. This results in an interrupt storm at
the MDSS top level.
This change removes the SW reset on the disconnect path and
relies on the SW reset that already exists in the connect path
to restore controller state.

The irq register and unregister calls in ppdone timeout
path can result in race condition which can lead to
scenarios where irqs will be enabled with no
callback registered. Add vblank mutex lock to avoid
such scenarios.

If there is unbalanced refcount for any interrupt, irq_stat_mask
does not get clear during suspend. On resume, enable irq is not
called leading to ctrl ISR permanently disabled. This is a defensive
check to recover from such scenario.

Add a sysfs mechanism to track the idle state of display subsystem.
This allows user space to poll on the idle state node to detect when
display goes idle for longer than the time set.
