[PATCH 1/2] dt: bindings: net: ath11k: add qcom,board_id definition

[John Crispin]

We need to be able to define what id the board has allowing us to load the
correct definition data. This patch adds the description of the required
property.

I was expecting this, there seems to be an option to add ranges and/or 
enums. I did however fail to find any docs on the schemeas.
