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.
