soc/tegra: fuse: Extract tegra_get_platform()
This function extracts the PRE_SI_PLATFORM field from the HIDREV register and can be used to determine which platform the kernel runs on (silicon, simulation, ...). Note that while only Tegra194 and later define this field, it should be safe to call this on prior generations as well since this field should read as 0, indicating silicon.
