disp: msm: dsi: add support for DMA CMD scheduling for CMD mode panels

Sfoglia il codice sorgente 
The change allows for configuring a command DMA window during which
the command is triggered. The DMA window must not intersect with the
MDP tear check window. Once the command transfer is successful, the
trigger control needs to reset to the default DMA trigger specified
by the panel.
