This patch set adds support for two features to get a finer control
over the impact of Thermal Throttling on performance.
1) Patch 1: Adds support to read Thermal fast Sampling Period (_TFP)
ACPI object and use it over "Thermal Sampling Period (_TSP)" for
Passive cooling if both are present.
2) Patch 2: Adds support to reduce the CPUFREQ reduction percentage
and not always cause throttling in steps of "20%".
Both patches can be applied independently.

v1[1] -> v2:
- Patch 1: add ACPI spec section info in commit description and rebased.
- Patch 2: add info about hardware in the commit description.
- Patch 2: switched CPUFREQ THERMAL tuning macros to static variables.
- Patch 2: update the tunings for Tegra241 SoC only using soc_id check.
