ARM: tegra: Disable pre-si features at run time
Disable the the remainder of the silicon only features at
run time instead of the Kconfig file. This change covers
THERMAL_THROTTLE, EDP_LIMITS and DYNAMIC_PWRDET.
Change HZ to 100 for all pre-si configs, not just FPGA. We
cannot change this field at run time. A faster tick doesn't
help sim or Qt CPUs go faster.
This change is a part of the effort to enable runtime
platform detection and reduce compile-time conditionals.
