Handle out of order dma fence signalling and propagation of fence
error. Out of order fence signaling is required only in Video mode.
For example, in case of N, N+1, N+2 frames where N, N+2 are good
frames and N+1 is frame with fence error. The release fence signal
sequence in video mode would be N+1, N, N+2.

Register callback function to hw fence driver and implement the
callback funtion.
As part of fence error handling, address out of ordering of HW
fences, SW override for release fence signal and handle BW voting
in both cmd and video mode.

This change adds hardware programming that will update the
txq wr_ptr upon output fence firing.

Starting pineapple, the output_fence trigger_sel register is updated to be
more controllable. Instead of hardware choosing the output fence timing
based on detecting if panel is in video/cmd mode, this is explicitly set
by software. Add support in display driver for to correctly write to
trigger_sel register for video mode.

This change adds debug changes to dump the input fences during a
commit done timeout, when input hw-fences are enabled.

This change adds support to wait on multiple hardware fences by
creating a fence array so each dpu-client only gets signaled until all
the hw fences going to the same ctl-path are signaled. It also
accounts for if a fence is a fence array.

This change disables hw-fencing for the last commit before
vm transition. This avoids configuration issues if hw-fencing is
disabled in the incoming VM.

Starting mdss 9.0, dpu supports triggering
the frame fetch through hw-fencing. This change
adds support for this hw-fence feature.
