Subject: [PATCH 4/6] dt-bindings: thermal: versal: Add description for Versal Thermal

From: Salih Erim <salih.erim@....com>

Add description of Versal Thermal which describes IO channels to
be binded to thermal. Constant channel of "sysmon-temp-channel" used as
mapped iio channel.

One temperature zone is used for the AI Engine temperature monitoring.
