[PATCH] arm64: zynqmp: Disable DP for Kria SOM

[Michal Simek]

DP is enabled via DT overlays and there is no need to have it enabled for
SOM only. Schema validation also reports that phys/phy-names are required
property which is not valid for SOM only DTs.

[Severity: Low]
Since enabling zynqmp_dpsub in the base SOM DT without phys or phy-names
broke schema validation and caused zynqmp_dp_phy_probe() to fail on
SOM-only DTBs, should this include:
