Add support to enable one-shot mode during qsync
update. This feature ensures the frame drops can be
reduced due to delayed software flush for the
current commit. Also, add changes to disable the qsync
feature post commit.

Allow Qsync and VRR features to be supported independently
by display driver. Restrict the feature availability in
same composition cycle.

CWB, DP and WB displays tear down sequence must reset
3d_merge, ctl, pingpong_binding, etc. MDP HW
blocks. This change fixes the tear down
sequence register programming. It also moves flush
sw reset before encoder_disable call. That allows
CWB tear down to update the flush configuration
on primary ctl path.

Log hardware interface framecount during te and vblank irqs for
command and video mode panels, respectively. This will help in
debugging any missed frames.

SDE driver triggers the frame and waits for the
ctl_start interrupt for command mode display. This interrupt
provides confirmation that hardware has picked up the
frame. Retire fence signaling is associated with
this interrupt and it is sent at the rd_ptr interrupt
after ctl_start. Due to lut dma delay, ctl_start interrupt
may be trigger before rd_ptr or after rd_ptr. SW manages
this complexity and handle retire fence for different cases
with 500us threshold logic.
This change replaces the ctl_start interrupt with wr_ptr
interrupt by programming it to trigger at 1st write line
count. This is guaranteed to come every time and it is close
to rd_ptr interrupt. That allows retire fence trigger at
wr_ptr interrupt and simplifies the SW logic. CRTC commit
thread would be held slightly longer with this change
as the wr_ptr is always close to rd_ptr and after
ctl_start.
