cpufreq / boost: Kconfig: Support for software-managed BOOST
Add CONFIG_CPU_FREQ_BOOST_SW Kconfig option such that software-managed boost is enabled only after selecting "EXYNOS Frequency Overclocking - Software". It also depends on the thermal subsystem to be compiled in, which is necessary for disabling boost and cooling down the device when overheating is detected. Software-managed boost _MUST_ _NOT_ be enabled without thermal subsystem with properly defined overheating temperature thresholds. This option doesn't affect the x86's hardware-driven boost support in the acpi-cpufreq driver.
