Primary and secondary displays should have first priority
when reserving lms. Static reservation can potentially block
higher resolutions for the required displays. This patch gets
the layer mixer requirement for primary or secondary display
if available. It reserves those layer mixers dynamically
for the respective display when connector is registered.

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.

Each mode_set call makes sure that previous frame is triggered
and triggers the esd check if there is pp_timeout. This may
lead to deadlock between crtc commit and event threads. Crtc
commit thread acquires the rc_lock and triggers the flush_thread
API on event_thread. Event thread again tries to acquire the
rc_lock to wait for frame. This can be prevented by avoiding the
pre_kickoff call from esd_failure notification if it is generated
through pp_timeout.

Reduce the log level from error to debug for invalid
master encoder in encoder restore path during idle
power-collapse. This would avoid unnecessary logging
when concurrent writeback gets enabled after a
power-collapse event, the restore happens based on
encoder_mask attached in the crtc before the actual
enable call for the cwb encoder.

On the first commit, cont splash flag is still enabled on
encoder, but connector is not yet attached. When a check-only
rm reservation is made, it does not get released due to
cont-splash check. If cont-splash is enabled, rm should
not check for connector, but directly release rsvp_nxt.

Userspace is not supposed to request vblank until crtc is enabled,
because drm framework rejects the request if crtc is not enabled.
Any vblank request prior to that need to be cached in the userspace.
Hence removing the cache logic from the downstream driver.

Current sde driver allows vblank enable and wait requests
even after crtc is disabled which would eventually lead to
enable of irq and timeouts in caller context. This change fixes
it by updating vblank callback status as 'on' during crtc enable
and shutdowns vblank callbacks before crtc disable is complete.
