ARM: tegra: hack to make IT parts operate like commercial temp for now
As NVIDIA so far was unable to provide us with any proper speedo
numbers for their industrial temperature aka IT parts just make SKU
0xB0 aka T30IQS-Ax behave identical to the regular commercial
temperature 0xB1 aka T30MQS-Ax for the SKU to speedo ID conversion.
This prevents them to fall back to fixed 600 MHz operation and crashing
thermal throttling once kicking in due to missing table entry causing a
null pointer exception.
