Enable compilation of DP MST feature. Also ported drm mst implementation to
use updated API definitions. Changes to the API include; removal of hotplug
callback; separate refcounting for topology and memory allocation in mst
port; pass the entire port instead of slot count in
atomic_release_vcpi_slots API.

If vblank work is queued to event thread, during modeset,
there might be a case where vblank is enabled in between
resulting in vblank ref count mismatch. This change queues
vblank request to disp thread during modeset.

Resource reservation of an atomic state should be cleared

consideration when it is greater than 2. This changes adjusts mixer

Reserve LM in the sequence of primary-peer and then
primary-peer again until all required LM are reserved.
Searching sequence will not change for single/dual LM
reservation. For single LM reservation it will return
right after the first primary LM is found. For dual LM
reservation it will return after the first primary-peer
pair is found.
The logic can also work for triple/quad or any number
of LM reservetion and make sure that all the reserved
LMs are in pairs except the last one if total LM number
is odd.

When a 4LM topology is used each plane attached to a CRTC
is tagged with a L/R layout value and an offset value
depending on where destination X coordinate lands on the display.
The layout information is used to determine SSPP to LM
pair mapping and local coordinate space.
This change also handles source-split and Z-order
validation checks for planes staged on different mixer
pairs.

With posted start enabled SW no longer waits for ppdone events
unless more than one frame is in queue. HW recovery logic relied
on these waits to know when we recover from a timeout. This
change moves the HW recovery SUCCESS event signalling outside of
the wait to ensure this event is sent to user-space regardless
of the status of posted start.

Setup blendstages is done per LM but FETCH_PIPE_ACTIVE is per CTL.
Overloading mixer blendstage setup with fetch pipe logic can lead
to HW programming errors. Refactor the logic for setting
FETCH_PIPE_ACTIVE by adding a new op that allows caller to provide
a bitmask of all pipes required to be active on this CTL. This new
logic includes support for:
- 4LM use-cases, staging pipes for all LMs within a CRTC
- Demura fetch-pipe without need for tracking via active_cfg (removed)
Also, lower the cyclomatic complexity in setup_blendstages by moving
the logic for obtaining the mixer config settings in to a helper
function.
