The interface resolution can be different from crtc/layer-mixer WxH
when certain features like destination scaler are enabled. Use the
sde_crtc_get_width/sde_crtc_get_mixer_width functions throughout
to get the correct crtc/lm size based on different features enabled.
This will help in validating/configuring lm & plane correctly.

Add a writeback connector property EARLY-FENCE-LINE to give usermode
the control on when to trigger the retire fence. This option is useful
in 2-pass composition, where the writeback triggers the retire-fence
early based on the prog-line which allows primary to start the fetch
before wb transaction is fully completed. This helps to keep the clks
and bw low. WB hardware generates the line-ptr-irq when wb output reaches
the configured prog-line. Retire fence is triggered based on the irq by
default and wb-done handles for cases where line-ptr-irq is missed.

Currently, writeback frame-triggers are serialized by default. Add
logic to support the different frame-trigger modes which can be set
through the connector property or encoder debugfs node.
- default: waits for frame(N-1) completion (wb-done-irq) before
configuring current frame(N) and releases the commit-thread on
frame-start (ctl-start-irq)
- posted-start: no previous frame(N-1) completion wait. Configures
frame(N) and releases the commit-thread on frame-start (ctl-start-irq)
- serialize: no previous frame(N-1) completion wait. Configures frame(N)
and releases the commit-thread on frame(N) completion (wb-done-irq)
(wb-done-irq) before configuring the next frame.
Restrict wb posted-start support only for MDSS 9.x+ targets, with older
targets defaulted to default-mode.

Avoid drm vblank on/off for virtual displays to allow drm framework to
ignore the vblank requests. Vblanks are unnecessary for writeback as it
is triggered based on the frame-updates and not on any defined interval.
In addition, avoid vblank callback registration for concurrent writeback
encoder.

The ROI commands are sent with an asynchronous command transfer wait.
If the queued CMD DMA wait for done gets scheduled before the DSI
controller timing engine programming, the later will be blocked waiting
on the ctrl_lock, which was acquired by the queued DMA wait for done work.
This effectively negates any advantage of having the async wait flag for
ROI commands blocking the main commit thread.
The change swaps this order to ensure that such a scenario never happens.
