Subject: [PATCH V2 2/4] dt-bindings: arm: ti: am642/am654: Allow for SoC only compatibles

Maintain consistency in K3 SoCs by allowing AM654 and AM642 platforms
just state SoC compatibles without specific board specific compatibles
aligned with what we have done for J721E/J7200 platforms as well.

Signed-off-by: Nishanth Menon <nm@...com>
---

Motivation to introduce in V2:
* Retain consistency with both "soc only" and "board specific" as two
  schemes we support across k3.

V1:  did'nt exist
