arm: tegra: set critical trips for Tegra124 



Set general "critical" trip temperatures for cpu, gpu, mem and pllx
thermal zones for all Tegra124 platform, these trips can trigger
shut down or reset.
Tegra124 Jetson TK1 was already set "critical" trips before, so it
can overwrite the general values.
