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.
