soc/tegra: fuse-helper: Add platform helper functions

Browse Source 
Various downstream drivers needs platform information i.e. if it is
running on silicon or simulation.

This patch adds following functions:
 * tegra_platform_is_silicon()
 * tegra_platform_is_sim()
 * tegra_platform_is_fpga()
 * tegra_platform_is_vdk()
