minui: Add support for low resolution display topologies
- Add a single layer mixer topology to cover low resolution
display framebuffer e.g. FHD, FHD+. Display is cropped
in absence of this topology.

Set the client cap properties for planes before
getting plane_resources.

Add support for 4 layer mixer staging logic
Currently plane staging logic assumes that only
2 planes (L/R) are required to drive the display.
When a 4LM topology is used, 4 adjacent planes are
needed to cover wider display resolutions.
This changes offsets plane src_x and dest_x coordinates
based on plane index and removes L/R assumption. It also
adds 4LM and VDC based topologies.
CRs-Fixed: 2672665
Test: boot-up test on 2LM and 4LM topologies
Change-Id: If33e9b22b5545e2187ab614eed390dfe09af56a9
Author: Prashant Beniwal <pbeniw@codeaurora.org>

Program required properties for 4 layer mixer
Legacy KMS driver expects planes to have different z-order
when staging them across two layer mixer pairs.
This change increments the plane z-order and programs
"zpos" optional property.
This change also adds missing connector-crtc association
property for the atomic commit required for driver to
recognize whether its a quadpipe topology or not.
CRs-Fixed: 2753034
Test: boot-up test on 2LM and 4LM topologies
