drivers: thermal: Move various drivers for intel platforms into a subdir This cleans up the directory a bit, now that we have several other platforms using platform-specific sub-directories. Compile-tested with ARCH=x86 defconfig and the drivers explicitly enabled with menuconfig.

# Makefile for various Intel thermal drivers.
thermal/intel: Introduce Intel TCC library There are several different drivers that accesses the Intel TCC (thermal control circuitry) MSRs, and each of them has its own implementation for the same functionalities, e.g. getting the current temperature, getting the tj_max, and getting/setting the tj_max offset. Introduce a library to unify the code for Intel CPU TCC MSR access. At the same time, ensure the temperature is got based on the updated tjmax value because tjmax can be changed at runtime for cases like the Intel SST-PP (Intel Speed Select Technology - Performance Profile) level change.

thermal/drivers/intel: Introduce tcc cooling driver On Intel processors, the core frequency can be reduced below OS request, when the current temperature reaches the TCC (Thermal Control Circuit) activation temperature. The default TCC activation temperature is specified by MSR_IA32_TEMPERATURE_TARGET. However, it can be adjusted by specifying an offset in degrees C, using the TCC Offset bits in the same MSR register. This patch introduces a cooling devices driver that utilizes the TCC Offset feature. The bigger the current cooling state is, the lower the effective TCC activation temperature is, so that the processors can be throttled earlier before system critical overheats. Note that, on different platforms, the behavior might be different on how fast the setting takes effect, and how much the CPU frequency is reduced. This patch has been tested on a KabyLake mobile platform from me, and also on a CometLake platform from Doug.

thermal: intel: hfi: Minimally initialize the Hardware Feedback Interface The Intel Hardware Feedback Interface provides guidance to the operating system about the performance and energy efficiency capabilities of each CPU in the system. Capabilities are numbers between 0 and 255 where a higher number represents a higher capability. For each CPU, energy efficiency and performance are reported as separate capabilities. Hardware computes these capabilities based on the operating conditions of the system such as power and thermal limits. These capabilities are shared with the operating system in a table resident in memory. Each package in the system has its own HFI instance. Every logical CPU in the package is represented in the table. More than one logical CPUs may be represented in a single table entry. When the hardware updates the table, it generates a package-level thermal interrupt. The size and format of the HFI table depend on the supported features and can only be determined at runtime. To minimally initialize the HFI, parse its features and allocate one instance per package of a data structure with the necessary parameters to read and navigate a local copy (i.e., owned by the driver) of individual HFI tables. A subsequent changeset will provide per-CPU initialization and interrupt handling.
