Subject: [PATCH] dt-bindings: thermal: Add bindings for gpu dump skip cooling
 device

Add bindings for gpu dump skip cooling device driver. This cooling
device is added to set WR_THERMAL_FLAG region in SDAM which is used
by PMIC to disable GFX in SDI path, when SDI path reset is caused
during high temperature. It also set a SOC cookie in sys dbg imem
region which is used to skip GPU scan dump collection in SDI path,
when SDI path reset is triggered during high temperature.
