Subject: [PATCH] t23x: nv-public: Disable hot surface alert for IGX

For IGX platform, the module and baseboard are inside the chassis, the
hot surface alert should not rely on on-chip or on-board thermal sensors
to judge whether the surface is hot or not. So, this change disables the
hot surface alert for IGX platform to avoid the false alarm.
