[PATCH v1 3/9] dt-bindings: thermal: imx: Add trips point

[Francesco Dolcini <francesco.dolcini@toradex.com>]

Add trips point to i.MX Thermal bindings for each temperature grade
(automotive, commercial, extended-commercial and industrial) to enable
specifying a different trip point than the hard-coded value.
