Add necessary checks during the splash init to check
& execute the splash/ramdump buffer mapping/unmapping
only for the cont-splash use-case. This would help in
reusing the same path for LE VM setup during device assign,
which does not have any splash buffer.

Increase the maximum number of mixers per crtc to 4 to
support 4LM use case. This change also increases the number
of data path to 4 to support 4LM in continuous splash handoff.

Fix resource and splash buffer handling in resource manager
and sde_kms to support continuous splash to be enabled/disabled
independently in multiple built-in display usecase.

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.
