Subject: [PATCHv2 1/2] dt-bindings: ath10k: Add new dt entries to identify coex support

This adds new dt entries qcom,coexist-support and qcom,coexist-gpio-pin
which will be used by ath10k driver to identify coex support
of a hardware and notify wifi firmware the gpio pin number.
This pin number information is needed for the hardware QCA4019.
