The cpufreq_driver's boost_supported flag is true only when boost
support is explicitly enabled. Boost related attributes are exported only
under the same condition.

Changes for v6:
- Replace exynos_driver.boost_supported = 1 to = true
- Protect boost attributes export with CONFIG_CPU_FREQ_BOOST_SW
Changes for v5:
- None
Changes for v4:
- None
Changes for v3:
- Remove low level boost code
- Move boost management code to cpufreq core code
- Use boost_supported flag to indicate if driver supports over clocking
Changes for v2:
- Removal of struct cpufreq_boost
- Removal of the CONFIG_CPU_FREQ_BOOST flag
- low_level_boost with valid address when boost is supported
